I changed the air idle controll valve & the coolent senser in the intake, started it up, had a really fast idle and after sometime, the service engine light came on. When I restart it, it will run really rough, then the sevice engine light comes on and it will smooth out to normal.
I have a hand held autoxray scanner, would like to pull the code but after taking the drivers side dash apart, there is no obd connecter no where to be found, what do you think of this?
