87 cherokee wont stay running
HELP!!!!! We have recently obtained a 1987 Jeep Cherokee 4x4 with the 4.0L Inline 6. We are using it for mudbogging and cant seem to keep it running. We thought it was overheating but have determined that the water temp gauge is not working properly and it is not overheating. We replaced the thermostat and have flushed the radiator just to be on the safe side. As soon as the engine is getting warm it is coughing and backfiring and losing all power. It will start up again after sitting for about 10 minutes. We have had suggestions ranging from we need a new fan to we have a PCM (power control module) going (or gone) bad. Looking at the Chilton manual it is not supposed to have a module. When we had the distributor cap off we did notice there to be a lot of oil in the distributor. We took that off and cleaned it out and the problem is still there and is getting worse by the minute.
Any suggestions?????
My husband is about to yank his hair out!! And any help would be appreciated.
Thanks in advance,
Chris and Brad
