Question about 1990 Chevrolet Lumina APV
I had the plugs and wires changed, and also changed the IAC motor. It is still idling rough and has a loss of power especially up hills. Like it isn't firing all cylinders. HELP!
On the chevy v6 engines it real comon to have intake leaks.I would try spraing carb cleaner around the intake while the car is running and see if it changes the way it runs.If it does that is your problem.If the intake has a leak it will **** extra air in and cause a missfire.
