    94 Camry
  1. 94 Camry LE automatic 104k miles. Just an FYI: Same problem for me...kinnda. In my case, cold car start is OK with RPM around 1100, then as it should begin to fall back below 1000 it jumps to nearly 2000 and holds there for several minutes. If I push accelerator, there is a big hesitation before the engine responds. If I try to shift into gear when revving 2000 RPM in park, car dies. Search the forum for Camry Stalls thread for more details on similar problem...all of which do not have a longterm solution yet.

    Camry Stalling

    Discovery made 3/12... FYI, my mechanic was ready to cave and change the fuel pump/meter/filter but after 30+ minutes of running a fuel line (pressure?) test on the 94 Camry and things coming back normal, he just wasn't ready to take it apart yet. So he quit for a day or two... Friday he took apart the throttle body again. Put it back together, still no improvement, but noticed an irregularity with air intake. I don't know how exactly to describe what he did, as I only talked to him on the phone, but he first verified there was no clog in the air intake leading to the air filter and leading from the air filter. However, air was not getting in the engine correctly. So, he took the entire assembly off (what exactly constitutes ENTIRELY I am not sure) and drove the car...and stopped the car...and waited...and restarted the car...and drove the car...and stopped the car...and waited..and drove the car...and stopped the car. Everything worked perfectly. Then he put all the crap he took out back in and the car went back to showing its old problems. So, at this point, he is trying to pinpoint a problem that seems to be between the air filter and the engine--or probably more realistically the EGR system as I think that is what the air intake feeds into. Keep your fingers crossed.

    Engine Dies

    I am beginning to think we should all drive (or tow, depending on our success) our Camry's to the Toyota headquarters... An update on my stalling Camry. It has gotten MUCH WORSE. To date we have done the following in the following order: -Tuneup (plugs, wires, air filter, yada yada yada) -Throttle body cleaning -EGR disconnected -TPS replaced -Distributor replaced -Oxygen sensor (don't know which or both) replaced None of these things have done anything to improve the situation. The problem has gone from intermittent to reproducible right down to the first intersection it will stall at! Car starts fine in the morning, although it sounds a little "hard" when it turns over. Shift into gear, things are great until the engine time warms up 2 miles from home. While stopped at light in gear, will feel a small on again/off again surge in engine and the "breaking" idle will be just over 1000 RPMs. If I let off break and switch to gas, there will be significant hesitation in engine...sometimes stall. I have resorted to keeping foot on gas to maintain RPM at 1500 while breaking at a light. When I get to work (only a 10 minute local drive) and put the car in park, the engine continues to rev at 1700-2000 RPM as before. Kill the engine now, cannot restart for at least 30 minutes. New problem after distibutore was replaced: if I am lucky and the car is idling normal in park after local driving, an immediate attempt to re-start will work, however, let 5+ minutes pass and the engine WILL NOT turn over. Cannot even flood the engine, suggesting a fuel related problem. Sometimes it takes 10 or more tries with me manually pumping gas to start car. Let the car sit for 4 or more hours, everything OK. Noticed just last night during one of those "gotta pump it to start it" experiences that I left a large spray of liquid on the driveway out the tailpipe. On that same trip home, the car started to sputter while driving it at 40 MPH but never stalled. I am asking my mechanic to look at the fuel pump, meter, filter, etc. again this week. Has anyone had fuel pump problems with their '94(ish) Camry? My mechanic says it is rare that the fuel pump goes bad on Camrys. BTW, Wandi, the ERG has to do with emissions (it lowers nitrous oxide emissions or something like that) and, as I understand it, is a component pretty much there because of government emissions regulations. Nonetheless, it can be troubleshot by having your mechanic disconnect a hose (labeled #3 on my EGR, I think, but it best left to the mechanic if you have never seen it done before) and plugging it with something like a golf tee. This effectively bypasses the EGR system. If the EGR is bad, your problem will have gone away with the EGR disconnected. If your problem still exists, its not the EGR. Our local Toyota dealer wanted to replace the EGR system and connected components for around $750.

    Camry Stalling

    For ToyotaTom... You finally broke down and took it to the dealer and they said EGR... Well what do you know. That must be the STANDARD answer as one of our local Toyota dealers said the EXACT SAME THING. In fact, the whole story went like this: Dealer Mechanic: "Mr Banik, we think we have found your problem. Your engine has a lot of carbon build-up, especially in the throttle body and the EGR valve. We cleaned the throttle body and that didn't seem to improve the car all that much. I've got the EGR system disassembled right now and I can see a lot of carbon--like strands of it, kind of like a magnet when it picks up magnetic dust. The EGR cannot be cleaned, so we will have to replace it. This means you'll be looking at a new EGR valve, sensor, VCV, water pump...yada yada yada [sorry, I cannot remember ALL the parts that were part of this EGR system overhaul]. Its gonna cost ya about $736." Me:"You cannot 'clean' the EGR valve but you are physically looking at it right now and can see the carbon?!?!" Dealer Mechanic: "Well, technically I am not looking at it right this moment. Our mechanics have it disassembled and say this is the problem. I am the customer service rep who places the call to you. There is another guy who actually drives the car too. But, yes, an EGR cannot be cleaned. Its very common for these to get dirty and need repair." Me: "So your mechanic can physically see and touch the carbon, but cannot clean it?" Dealer SERVICE REP (now that I know what he really is): "Mr Banik, I am not trying to be difficult here. We see this kind of thing on a regular basis. We could probably spray some stuff in there like we did to the throttle body [at a cost of $35 I might add] but it won't help any." Me: "Put the car back together. Do not replace anything. I will pick it up after work." Dealer SERVICE REP: "I understand Mr. Banik. That will be $170." Me: "$170? You told me it was $35 to spray stuff on the throttle body to clean it!" Dealer SEVICE REP: "Yes, $35 for the cleaning--that's 1/2 hour of service. Plus the diagnostic fee and the time for us to analyze and drive the car to recreate the problem." Me: "Just get my goddamn car put back together please." ------------- Long story even longer... I took all this info back to my neighborhood mechanic who disconnected the EGR to troubleshoot it rather than start throwing parts at it. Car ran well for 2-3 days with EGR disconnected (temperature for those couple of days was a dry 45-50 degrees), then started to exhibit the same stalling symptoms: hard crank to start cold, engine rev high in park/neutral (2000 RPMs), sputter/stall giving gas coming out of complete stop at light and/or stopsign, stall engine completely if shift from high 2000 RPM park to Drive or Reverse, cannot start for 30-60 minutes after stalling. As of late, the car will even LUNGE (due to fluctuating idle RPMs) when sitting at red lights. I almost bumped a guy in front of me the other day WITH THE FOOT ON THE BRAKE!!! Now I two foot drive when the car is not in the shop. I am getting the TPS (throttle position sensor) replaced today. Mechanic is very sure there is a problem with the TPS he hopes related to the part, and not some other computer component. He is also troubleshooting the MAP (mainfold air pressure?) sensor as he is beginning to think there might be TWO problems manifesting themselves at the same time. :censor:

    Camry Stalling

    The saga continues... We, as of Friday January 9, have discovered a bad TPS (Throttle Position Sensor) and bad MAP (Manifold Air? Pressure) sensor on my regularly but randomly stalling, fluctuating RPM at idle, 104,000 mile, 1994 Camry. Hope to have both replaced next week. No idea what the parts cost, though. Anyone paid for a TPS or MAP? Looking for estimates on parts cost. Thanks.

    Camry Stalling

    Alas, I spoke too soon. The stalling and high revving in park is back...and the car is back in the shop after 4-5 days of perfect running. Next thing to look at is the distributor (ignition coils?--I am pretty ignorant on this) according to my mechanic who has ruled out the EGR thanks the to problem coming back AFTER we disconnected the EGR. We also noticed very little dirt on a now 4 month old air filter making ME wonder if there is a problem with general air-flow in the engine. Nothing clogging the intake leading to the filter, but man that filter is as clean as the day we took it out of the box. DID YOU EVER GET YOUR PROBLEM RESOLVED?

    Engine Dies

    Found a mechanic who actually TROUBLESHOT my problem!!! (Other mechanics wanted to change timing belts, upgrade to platinum plugs, replace distributor, water pump, etc without being remotely possitive any of those things would fix the problem.) He "disconnected" the EGR system effectively taking it out of the mix for a few days. The car can be driven without the EGR system active (might experience some engine knocking noise when EGR is bypassed) to rule out (or in) the EGR system. We also cleaned the throttle body which was gummed up but did not solve the car stalling and idling HIGH (2000 RPMs in park) before dying. Its been 2 days without the EGR and my Camry runs like new again...knock on wood.

    Camry Stalling

    I have a 1994 Camry stalling with no warning and under similar (but also broader) situations. After 2 months of mechanics, I finally got one to disconnect the EGR system (bypassing the EGR valve) and we appear to have "fixed" the stalling problem (would stall on hard break, sometimes while idling at a stoplight or accelerating from a complete stop at a sign). You don't "need" the EGR to drive the car, so its something that can be dissengaged for a few days to troubleshoot your problem.

    Engine Dies

    Add me to the list of '94 vintage Camry (4-cylinder, 140k miles, automatic) owners perplexed by the "stalling engine" problem. Our mechanic (non-Toyota) initially could not recreate the problem. In the infant stages, the engine stall was very difficult to replicate. Plugs, wires, etc were replaced as part of a standard "tune-up" as the starting point of troubleshooting. After stalling on route to a shopping mall, we had the car towed. Of course, 1 hour passed from the time the car stalled and the time they came out to pick it up. To our shock, the car had started with no problem (made me look like an *****). Now, we can replicate the problem daily as I have resorted to "two-footed" driving between trips to the Toyota dealer's service center. Start the car cold, drive through the first few stopsigns in the neighborhood and it feels as good as driving a brand new car. Sit at the first light (3 minutes into driving, 1.25 miles from home) notice a little bounce in the RPMs from normal idle of 800ish to 1250-2000 RPM. Give it some gas, get a sputter but no stalling...yet. Get the car up to 40MPH over the next half mile, stop for a lefthand turn, feels like its gonna let go when breaking. (This is where the two-footing comes into play). Complete the drive the remaining 2 miles to work through lights and signs with two feet forcing the RPMS to stay between 1000 and 1250, car is fine. Turn into parkinglot, almost lose engine. Put the car in PARK, engine revs 2000 RPMs (or higher) for a good 3-5 minutes before dropping off to regular idle. Stop engine, car is dead for 15 minutes to an hour. It sputter on the re-start attempts, teasing you into thinking it might actually start! Hour later, starts fine, drives fine again for 5-10 minutes then repeats its problem. Another weird item of note is that if I maintain a speed of 20-25mph, I can feel the car wobble left-to-right very rhythmically. Any other speed this does not happen. Non-Toyota mechanic says he has heard of distributor problems with this vintage Camry. He says he has NEVER had to replace fuel pumps in 94 Camry's. Toyota mechanic says nothing on diagnostics, wants to replace the timing belt. My regular mechanic is skeptical. Toyota mechanic noted build-up of "gunk" on the throttle (or throttle valve? I don't recall exactly what he said) and cleaned it. Verdict is out on the cleaning, a decision is yet to be made on tackling the timing belt issue. No oil leaks, white smoke, etc. Another oddity is the "freshness" of the air filter replaced 2+ months ago. Looks as clean now as it did when it came out of the box. Checked the intake leading to the air filter and there were no squirrels nests or anything blocking the intake TO the air filter. I am helpless at looking past the filter into the engine. I love my Camry, but this is maddening! :ffs:
