Q: Possible vacuum leak causing engine to rev while parked.

asked by on

Engine revs while in park. Someone suggested it might be a vacuum leak.

It is possible that you may have a vacuum leak and if you do the computer will generate a code for system too lean. I would have a technician come out and inspect the codes on the computer and see if you do in fact have a vacuum leak.
