92 mildly built 4.0 5 spd in a 90 BII. I have a misfire that occurs once every 5 to 10 miles and sometimes the check engine light comes on then goes off(Shop could not pull a code). Changed fuel filter, plugs, ignition coil, and air filter. Runs perfect under load through 5000 rpm's(in all gears-did not try 5th of course)-it is just the normal load driving.Does this both when cold and when warmed up. 64,000 miles on motor with no ticks or rattles of valve train.
