Re: Engine Stalling/Idling

When downshifting from 3rd to 2nd and lifting the clutch out it will stall majority of the time BUT on the odd occasion I've been able to get into 2nd and quickly make it into 1st where the revs will flucuate and will sometimes stall or will simply idle like a normal tank.

I've taken the MAF off and it was pretty much spotless but I gave it a clean regardless but haven't fitted it back yet.

What I plan on doing is:

Taking off the IACV and giving that a onceover
Boost leak test

Second problem, it takes my car 4 tries to actually get it running and even on the fourth try I have to floor it to get the revs up.

By four tries I mean:
turn, stall
turn, stall
turn, stall
turn, WHOOSH

For every single attempt I am depressing the acclerator when it catches.

Anything else that could potentially cause these problems?
Thanks
I dont think you need to do the IACV if, once it is started it is idling fine. A boost leak test will only show if there may be a problem whilst the car is actually in boost and from your symptoms, that doesnt appear to be the case.

A faulty MAF would definately cause stalling issues. Have you tried running the engine then unplugging it? If the engine carries on, the MAF is fooked. If it stalls, then the chances are that the MAF is fine.

Have you changed the fuel filter? I had problem starting mine until I changed it. Now it starts first time, every time. You shouldnt need to press the accelerator pedal at all. In fact I found it made things worse. Just turn the key and it should fire within a second or 2.
