90 T-Bird SC which bucks while under power after about 20 minutes of driving. After pulling over, and turning off the key, it will grind consistently for about 3 minutes (as though looking for a good spot on the distributor, which it doen't have) and will turn over. At this point, the RPM gage registers 0, and runs fine. After
5-10 mins the RPM gage returns to normal. Fuel pump, and filters have been replaced. Mechanic not much help. He ran the codes, and could find nothing electrical. Friend told me that if the check engine light is not on, there will be no codes thrown.....any ideas?
