fuel problem

exiletalon · Mar 3, 2006

I continue to hit a fuel cut like barrier at around 4-4500 RPM, I cant understand what the issue is! The motor ended up blowing. So i replaced it witha nwere lower mileage motor. ( 95' TSI AWD/ 97' GSX motor) But the fuel cut issue persisted. I still have the same turbo and FP, but thats about it.- so it could it be the wastegate or the FP. S16G turbo, stock fuel pump. HELP PLEASE!

I'm waiting for another PRO to answer this one, but do a boost leak first on the setup that you have...if it turns out OK, then most likely you got a bad ECU.

Boost leak test is the 1st thing to always try when your having fuel cut issues. Odds are you wont have a boost leak if your car is doing the same thing after having everything apart and replaced. Do a boost leak test and pressurize it to 20-25 psi and see how long it holds (watch your boost gauge). If that comes out alright, I would borrow and ECU from a local and try that out.
