Last few times I have taken my wagon out, I have noticed a slight stumble while cruising at about 65. It is the only thing that happens. temp and oil pressure are fine. unfortunatly it is so intermittant I don't think I can recreate it myself. Any Ideas what it could be???? Tim
Difficult to determine whats going on with it. Maybe the wires are arcing out? Take a squirt bottle with water and soak the wires down. Rev it up and see if it starts skipping a beat.
Its pretty cold around here this time of the year Possibly the engine was a little lean during warm months,and now you are having a lean cruise misifre going on? Good Luck
New fuel filter and new points if you are not running HEI. If you are, take a real good look at the pickup coil leads where they attach to the module.
