1993 Ford Explorer XL 4.0L Poor Idle Quality, Surge
Hi Group; This explorer is making me crazy with an idle problem. It sounds to me like it is backfiring into the intake very randomly. I have shorted out each plug wire in an attempt to narrow it down to a single cylinder but no luck. I disconnected the "spout"...
