siraireparker Posted July 2, 2008 Report Share Posted July 2, 2008 I back it out of the garage, it's running fine. I leave an hour later, it's running rough. The boost gauge is at -20 PSI at idle and slowly rises as I give it more gas. I can't feel the turbo boost even when the boost guage gets to +7 psi. It feels rough the whole time. Any ideas?

Dcrasta Posted July 2, 2008 Report Share Posted July 2, 2008 Timing? Disconnected IC hoses ? Vacuum / induction system leak? Bad Coolant temp sensors Bad spark plug wires? (Weak spark) Bad fuel? Link to comment Share on other sites More sharing options...
dj_justice Posted July 2, 2008 Report Share Posted July 2, 2008 I didnt know you could go into negative PSI boost lol. I think you meant 20 in. HG. Sounds to me like a boost leak. Link to comment Share on other sites More sharing options...
siraireparker Posted July 3, 2008 Author Report Share Posted July 3, 2008 It was a vacuum leak. All is right with the world. Thanks for your responses. Link to comment Share on other sites More sharing options...
