95 Sierra missing and-backfiring out of throttle body after swapping out ICM
My 95’ GMC Sierra burnt up two ignition control module when we replaced it with a new one this last time it caused it to miss and backfire out the throttle body, the the trucks been starting off and on, some days it will and some days it won’t. What could be causing this?
