ex3cutiv3 · 10-31-2006, 11:18 PM

Hey I have an 89 turbo and it runs but the turbo doesnt seem to. On the road tho sometimes the stock gauge would jump to 8 psi. It sits on the 0 when driving and -4 when its idling. ALso it puffs out random white smoke and it runs absolutely perfect otherwise!!?? ANy suggestions? Thanks

Correct me if I'm wrong, but that sounds like the way a stock turbo is supposed to act. At idle it has negative pressure, no exhaust pushing the turbo. At normal driving to slow acceleration it could be 0-4psi and under full acceleration hit 6-8psi?

i understand that but under full accel it says 0 and at normal drivin it will pop up to 8 then downto 0 instantly.

Does the car feel like its under boost when you accel or does it feel boggy and slow? could just be a bad gauge.

Do a diag

From what I've read from other posts here my might have a vacuum leak somewhere. If I had a turbo I'd be of more help but I'm just a N/A

does it feel like its boosting normal when you hit the accel or when you hit the accell you get no boost?

might have a leak under heavy boost

I had already done a diag and it came up a 52 (knock sensor) and that was all.

Also the car is not boosting wat so ever.
