rev up and down in park
When I put it in park after driving it it revs up 2000 psi's and down and up Do you know what causes this?
idle air control valve should be on the back of your intake manifold with 2 wires going to it and 2 coolant lines.
Thank you Takoda!!! Most helpfull!
same thing happened to me... either a bad IAC or a dirty intake manifold...or probably a vaccum issue?
Thank you Anthony! I will check both!
does this make your valves to burn up. i have the same problem when in neutral at a stop it rev's up and down. and i have a valve tapping but my oil level is fine.
