How to tell if an IAC valve is bad?
I turned on my truck and unplugged the wire that goes into it and the truck turned off. Does that mean it's working or not?
My truck is idling so bad it will stall and spudders my truck and make the oil psi run 0psi or so.
Driving is no problem because it reads between 25-50psi.
