Thread: Ok need a little help

OK so when i turn on my Car it will turn on and shut off right away. If i hold the gas for a bit the car eventually idles out fine.




Now been doing some searching and found it could be leaky injectors. So i took the rail off and turn the ignition on none of the injectors are leaking. Did also a pressure test and found no leaks

Any ideas

how about the iacv valve? is it dirty

same thing i was thinking, or maybe a vaccum leak.

ive had a leaky iacv and it would do the same thing until the car warmed up, but when slowing down with my foot of the gas it would want to stall out.

stratton.

the iacv is normal there for cold starts if its clogged or dirty this can cause exactly what you are talking about....my car is like that, when i start it and its on a fresh cold start it will start die, start die, start die, and i will have to keep the rev till it gets semi warm....and i know for a fact my iacv isnt 100% so i would start there....after a while my car will idle just fine like you said

i clean the iacv so it should be ok, should i just get a new 1

i would try and clean it before replacing it

i did and the same thing

Isn't there a cold idle start issue with our cars? I don't know what your setup is, but IIRC there's a cold idle start issue that JWT and Calum both correct, in order for your car to run decently during cold starts...

machanical wise im pretty sure the iacv is mostly the resoning for the cold idle start issues....not sre about ecu contributing to the problem

it is a G20 ECU /with SAFCII
