Boost gauge sometimes stuck...

Ok this is a vacuum leak of some sort when its showing boost (small like 0.somthing) when Im not even touching the gas right. Just double checking.

you should be pulling like 16-20 in of vaccum at idle

ok lol. you lost me. Does that mean that usually means a vac leak when I could just be cruising and boost is stuck at 0.1or 0.2 lol

can your gauge read actual vacuum or just boost???

Vacuum is below 0", so he is saying at idle the car should have around -18ish vacuum.

Just boost. I wouldnt imagine it just reads a little boost for fun

Sell it and get one of these kinds.

They are way better and can help with diagnosis on the motor.

LOL I have a GS so it actually reads out a number not just the red bars GTPs have. It would be a nice upgrade tho
