I need to know if any one can give me help with a problem. I have a 1993 tt stealth when you crank it up it runs rough. for about 45 sec then the boost guage starts to show pos boost. the rpm is only 1200-1500rpm. after about 2 minutes the boost guage pegs at 14lbs. the ecu floods the engine with gas because of the amount of boost. the exhaust is a cloud of blue an gray unburned fuel. i have changed every thing on the vaccum side. any suggestion would be helpful.

 

Sorry, I cannot help you out with that one. I don't know enough about turbos to give advice....but,
3si.org US3S.org

Check out those two sites. They are platform specific to the 3s (Stealth's and 3KGT's) and someone there should be able to help you out.
