    Camry Stalling

    Sorry I didn't reply sooner. I'll throw up a pic later on of what I changed just to see if it's the same as you. Let us know your results regardless - I hope it cures your problem like it did for me. j1s15n: seems like a you may have had a different problem after all, especially if your symptoms weren't temperature dependent like the rest of us here. Glad to hear you've resolved your issue.

    pnyklr, did you actually read what I wrote ?? <_< j1s15n, just because you don't see black smoke come out of the tail pipe doesn't necessarily mean your not running rich. Does your car have difficulty starting when the engine is still hot? Do the symptoms only happen after the car gets warm/hot? Most of the cases here are very much temperature dependant.

    Camry Stalling

    Problem found and resolved on my fiancés 92 Camry: coolant temp sensor. After exhibiting all the same symptoms as you all, I went down to the Toyota dealer who misdiagnosed the distributor and igniter as being at fault. After they charged and arm and a leg, it stalled at the next stop light on the way home. Furious at Toyota, but tired and wanting to get home, I waited for the car to cool enough for it to start again and carefully drove home, doing the gas/brake deely with both feet. I then took the car to a friend of a friend, a trusted non-Toyota mechanic that came highly recommended. He had the problem figured out and solved in 2 days. As I came to pick up the car, he explained to me what he did and how he figured it out. He had a snap-on computer, just smaller than the size of a laptop hooked up to several sensors in the engine compartment; he actually drove the car with wires hanging out of the hood going through the window to his computer, which acted like a real-time analyzer and data logger. As soon as the symptom arose, it was the temperature sensor that caused the fault. As most of you may know, temperature sensors are just over-sized thermistors, which are devices that output a change in resistance in proportion to the heat that is detected. The ECU measures this resistance to determine the temperature of the engine, and based on such, gives the appropriate amount of fuel to cylinders to combust. The problem is that over time (at least so I've been told with Toyota temp sensors), they can fail after getting to a certain temperature. They would function cold and as they get hotter and hotter, they short/open and produce a false reading to the ECU. The ECU then sees this as a malfunction, and thinking that the motor is cold in an effort to avoid detonation, dumps WAY more fuel than needed and basically floods the engine. This is why after the car stalls and you try and start the car unsuccessfully, you can smell a heavy gas odor in/near the engine compartment. It's putting too much fuel for the temperature of the motor/air and stalling the motor. This is also why it stalls only when coming to a stop: because you don't have your foot on the gas to let more air in to balance out the extra fuel that is being sent into the engine. Apparently, this is something of an issue with Toyota coolant temp sensors after a long period of time (at least told to me). I'm so ****** off with the Toyota dealer you cannot imagine. They cringe whenever I go down there because they couldn't fix my problem and charged me for something that wasn't even causing the issue. As far as I'm concerned, dealers can only fix problems to which they know the cause of, and do not know for the life of them how to troubleshoot issues! For this they can all go :censor:. I tried all the other suggestions here before sending it to my friend's mechanic friend, with no resolvement. And no offence to anyone that offered such suggestions, but I was skeptical of them to begin with because none of them really seemed to be affected by heat, which our problem does. I did find comfort knowing we weren't alone in this, and thank you all for this great site and thread - in which I found by google. After replacing the sensor, not only did the problem go away completely, but our gas mileage got considerably better, and the car exhibited a lot more power when hot. I hope this info will give you some insight to your dilemmas of the same nature, and provide you with much needed relief - and a good nights (worry-free) sleep! Kind Regards, Ive Vancouver, BC P.S. If anyone needs a perfectly working used distributor and coil, courtesy of my local Toyota's misdiagnosis, email me as I have one for sale. :)
