Im park or waiting on a redlight, I notice my jeep idleing rouph. My RPM gage holds steady, not jumpin or jerking. The only thing I notice is my oil gage pressure slightly jump, its barely noticable. Need a clarification on this, anyone? 1993 JGC L6 4.0
Thanx

Replace your spark plugs, distributor cap and rotor, and let us know if there is any change.

Thanx on that advice, nail it! Im still having a RPM surge while Im doing 65 to 70, the tug is slight but you can still feel it.
