ideal problem

[blackslide]

no this isn't the normal MAF problem it revs up goes fine just alot of time when i come up to a light or stop sign and have to down shift the car will die and it will start right back up i'm wondering if this could be throttle position or something else.

check your IACV? the problem is only occuring in decel correct?

[IanS]

are you running atmospheric bov

I had the same problem. Found out my IACV hose that attaches to the cold pipe came off, causing the car to die whenever downshifting to first. So check your IACV setup.

thanks for the help i'll check it

Boost leaks and leaky BOV(or VTA) can and will cause this too.

[Deadrodent]

VTA?

what's the most efficient way to check for boost leaks? my car does this also but it's an occasional problem it only happens sometimes...

[CoupedUp]

VTA = Vent To Atmosphere.

I would get a piece of PVC pipe end cap the same Outside Diameter as the turbo inlet and attach that there with a hole drilled into it with a compressor fitting threaded into it snugly with teflon tape. Then pump it with some PSI. And listen.

hmm not sure i have access to a compressor...guess i have to fire up the ole' lungs
