94 Explorer backfire mystery
Backfires when coasting in gear (first thought it was a rear axel problem the way it grabbed and bucked). No other drivetrain issues under power.
Garage guys, always have been excellent, are mystified. Changed plugs, checked ignition, timing, etc. Unable to diagnose the problem.
Anyone heard of a rare or unusual problem with these symptoms,and know what might be wrong?
94 Explorer, 5 speed
