I got couple problems I was wondering about. When ever I go into boost, its fine but when I let off the gas it keeps accelerating for a brief second and I don’t know why. It doesn’t do this when I’m not boosting. When the fans cut on do they both cut on? Whenever I park my car with it still running, the fan on the driver’s side only cuts on; I never see the other one cut on. I’ve also noticed on the gauge that I’ve been getting –5 hg’s for my vac. at idle, but she idles fine. I read that I should be getting 18-20 hg’s. There is this black vac tube that sits on the PS that’s not connected to anything. You guys got any idea what it hooks up too? Could I be loosing my vac. psi through this tube?

Both fans should come on when you run the a/c, only one without when it starts to get hot. That black tube should run to your evap canister in the lower pass. fender, if you don't have it block it off. And check your throttle body/cable to be sure it's not sticking.

Well don't i feel like an dumb ass, my POS K&N Filter popped out and was hitting the throttle. found the evap. line and plugged it back in. Still got a reading of 5 hg's, its plugged in via the AEM sensor for the TRU boost gauge so its gotta be accurate. Did a leak down test found nothing. I'm not too worried about the vac. because the car runs great for now that is. THANKS
