Q: Possible vacuum leak on my 2005 PT Cruiser. How bad is it?

asked by on

When stopped or in park I could hear my engine revving high over and over and looked to my rpm scale and my needle was bouncing between 1000 and 2000.

My car has 90000 miles.
My car has an automatic transmission.

You may have a vacuum leak in the intake air tubing between the turbo and the throttle body or mass air sensor. I would recommend having the engine checked and diagnosed by a certified mechanic from YourMechanic.
