RPM Jumps after head gasket replacement
I have been searching and trying different things but I am losing patience. I have a 2005 Honda civic. I just replaced the head gasket due to overheating. I didn't have any idle problems before.
When I start the car the RPMs jumps up and down constantly while in park. I have checked and cleaned the idle control valve but it has the same issue.
I am going to bleed the coolant again tonight and see what happens but I can't figure out what happened.
