Runs Rough When hit bump

[Jeepsburg]

Hello, I got a 1989 YJ, inline 6 4.2 manual engine and...

My jeep used to run real rough when it got hot, i then replaced the distributor and it still did not have real good power so i cleaned out the carb and replaced the Ignition Control Modual, but it still losses some power when ever you hit a bump. I sputters very slightly.


Anybody got any ideas? Thanks, Jon.

check your grounds... something could be getting loose.

My first thought was a bad ground. Second thought was to replace the crap Carter carb with a Motorcraft 2100.
