85 bronco 4.9 L6 carburated cuyys out on the highway
85 bronco 4.9 carbureted 6 engine turns off for a few seconds, then turns back on for few minutes then turns off again for few seconds. when this happens clunking of the drive train happens. this only happens while cruising at highway speed, pulling a long hill r pass it does fine,and in town no problems. I have replaced the pick up coil,and modual. what could be causing this? trouble codes of 22, 41,63 could TBS cause this?
