  1. Hello folks, in the middle of fitting a 1zz throttle body, injectors and intake onto my 4zz and have a question. There are two lines that run coolant too and from the throttle body, can anyone tell me what line goes where on the 1zz vs the 4zz. I took an educated guess matching the lines between the two (yellow/green cable ties) as the pic below will show, but can anyone tell me if i've gotten it correct? What concerns me was that when installed and running when hooked up as shown, the part of the throttle body the coolant runs through started to get quite hot, hotter than i would expect it to get for running for the length of time it did and i don't want to damage it.
  2. Hi and thanks for your reply. Managed to source the issue. In my research i watched a video of someone installing fogs into a 2006 model. The 2006+ models have a fog light relay in the fuse box in the engine compartment, where as my two older cars have a hidden 3rd fuse/relay box behind the spare change compartment just under the ignition barrel. I noticed the donor car had relays installed in it where mine did not. I transferred the relay from one car to the other and the fog lights started to get the correct voltage. There was another purple relay installed in the donor car which i can only assume is for the A/C as the other one doesn't have it either.
  3. Hi folks, quick question as i'm a bit stuck. Recently bought a 2003 t3 corolla for spares for my 2004 t2 car. The parts car came with fog lights on the front and i'm in the middle of installing them. Before removing them from the parts car i confirmed whey where working. I've the indicator stalk changed and working fine with all the normal functions and have installed the t3 cars fog light relay, but when installing the passenger side fog light to test it doesn't seem to be getting the full voltage. On a volt meter with the fog lights turned on the pre-existing toyota wiring harness is only giving out 0.8 volts. I have not installed the drivers side fog light yet as the car is due mot in a weeks time and if they do not work for the test the car will fail. Any idea's what could be causing this?
  4. Funny you mention it, i never said on the post but i noticed the dive in fuel efficiency after i filled up at a recently opened manless "go" petrol station. The car starts, runs and drives fine, just feels a little more docile than normal, especially in lower pre-vvti rpm. Another friend suggested it could be a dirty fuel filter, i don't see how this could cause the issue but i'll replace it anyway for all they cost. I don't believe its a maintenance thing such as spark plugs or air filter as the fuel drop was immediate, not something thats gotten worse, but the plugs are around 15k miles old so will replace them while i'm there.
  5. Hi Guys, Car : 2004 1.4vvti corolla Roughly 3 weeks ago my car took a nose drive in MPG, going from about 340miles to a tank to struggling to reach 260. The extra fuel usage is very evident when travelling at speeds around or above 60mph (2800rpm+ in 5th gear) I've been told this could be caused by clogged air filter, faulty MAF or damaged O2 sensors. There is no EML on and the car drives fine but feels a little more sluggish than normal/ I've checked the air filter and its clean (relatively speaking) i cleaned some dirt and oil residue from the MAF and neither seemed to have changed the MPG issue. After looking online and speaking to a mechanic friend i was told you can test the o2 sensor by measuring the resistance, i checked the pre-cat o2 sensor (been told the pre-cat sensor is the one that usually fails) and got a reading of around 8.1 ohms, which i believe is within tolerance (can someone confirm this?) I've yet to test or check the post cat o2 sensor as i've had limited time to crawl under the car. What would be your recommendation for the next step to find the issue?
  6. Hi folks, I've a 2004 1.4 Corolla, have read online about how people get good performance gains by installing 1zz-fe intake manifold, throttle body and injectors to the 4zz The question is, most people who perform these mods do it to a 4zz-fe engine where mine's a 4zz-s52, will the 1zz manifold, throttle body and injectors still bolt in and work without needing additional parts or ECU work? And can anyone tell me what the differences between the 4zz-fe and the 4zz-a52 are? Thanks
