Vehicle normally runs great. But sometimes when on the hwy using cruise control (60-70 MPH) and going uphill, the car will miss/roughness. It only lasted a couple of seconds ( I disengage the cruise control), and I get a check engine light. "Miss in #4 cylinder". After driving an hour or two the check engine light goes out. I tried to duplicate the problem without using the cruise control, and I sometimes can get it to miss/roughness. But, I immediately let off and do not get a check engine light.
It recently had new plugs, dist cap & rotor.
Since the problem first occurred I swapped the #4 spark plug (it looked fine), and checked the plug wire to #4 cyl, everything was good. I have also tried different gas stations and used Lucus gas additive, with same results.
Normal driving around town is no problem, and the 1000 mile trip (interstate miles) I only had the problem once, but I could sometimes duplicate it by trying to pickup speed while going up hill. All other times it runs fine.
