hey all
I'm having an issue that started intermittently and now its happening every time i start it,
basically every time I start the car it fires up perfectly, no hesitation whatsoever. However as the water temps get up to about 65-70 and oil temps about 50, it starts to idle very low, and then eventually it cuts out.
The car then wont start at all. Now before it dies I can keep the revs up and its no problem, no misfires, no hesitation etc and runs smooth. Its just when it idles and cuts out or if I switch it off, and then try and restart it, it just refuses to start until its cold.
Now I immediately thought coolant temp sensor, however as the right hand warning lights were not working (typical dry solder joints) I couldn't pull fault codes. I changed it anyway for a new Toyota item and it didn't fix it. I then proceeded to fix the warning lights and did the diagnostic test and its showing absolutely no faults whatsoever :S
no the cars fitted with a afr gauge and its reading as expected, rich when cold and then near stoich when warm, so the standard oxygen sensor is working (if it wasn't then it would be irratic)
its obviously something to do with the open loop system, but i'm unsure what to do.
