I have been having problems and posted a few times. My boost gauge was reading -2 to 0 and my idle was very rough and it sounds like shit. I replaced wires, plugs, IAC, throttle body, PCV valve, 02 sensor, has new sensors, and some other stuff i cant remember. I also redid all my vacuum lines. I installed 42lb injectors but that was after it was already having problems so it cannot be that. No clue, i thought it was timing and they said it was not timing and they say it is a vacuum leak. It was -14 and for it to go to -2 is a big leak and i cannot find any or hear any leaks. Could something be clogged or any leaks from exhaust cause this. Any suggestions what to check or what to do. Please, this is all i need to fix so i can get my car running good after being rebuilt and installing bigger injectors.

as far as leaks go... if ur goin to leak test vac system your goin to have to go over every connection and make sure its tight and connected properly. i'm fairly certain that you won't hear that leak. your exhaust wouldn't affect the vac drop either. take the time and go over ur whole system. i'm sure you'll find the problem.

Thanks, i hope the guys will try and do the test where you check for pressure being lost and a leak down test if that was its called. I know i will soon find out what the hell is causing this.
