Bought a 1g, And has Stutter/Stall problems.

[Viva]

1992
Talon TSI AWD
16g Turbo, FMIC
MAF sensor and Tranlator.
Complaint: Idles Rough, Stalls when coming to a stop,Car hesitates and runs rich and lacks performance after 4000 RPMs.
Just bought this car, did a leak test on it, all good results on that... still not sure about why it stalls.

I have a Wideband on it, reads all over the place at idle. Under boost (10psi) reads rich.

Help me out guys, thanks!

I have a feeling it is related to that maf translator. I would try running a 1g maf and seeing what happens. What do you mean by leak test? Boost leak test? Or leak down test? Both should probably be done, and if not leak down, at least a compression test. That will rule out any major issues.

Boost leak test. I took the maf out looked at it and cleaned it with proper macf cleaner. I hooked up an oscillation scope and all read good. Is it the tps?
