PSI Stuck at Zero

[Badarse97]

Hey whats up everyone. I drove my car about 50 miles today. it started running crappy after i got off the highway. i was getting really bad idle surges at red llgithts (almost staling).

main problem im having is the boost gauge is reading zero at idle. same thing when i drive off. if i give it some gas it boosts up a little bit. if i rev the engine the gauge will vac. to about 15 but slowly rise back to zero. tried searching the forums and i couldnt find anything about it.

You have a boost leak. Search "boost leak test". It will help you out.

check your fpr lines ... and vacuum lines on the intake manifold , ripped or loose...

and go ahead with that boost leak test...

I agree with others that you have a boost leak. I would first check all off your intercooler pipings connections as that is the main reason behind most boost leaks. They're fairly easy to find sometimes without doing the leak test first. Good luck.
