My 1999 dodge neon highline has 935000 miles. The check engine light came on about 5000 miles ago (i'm disabled w/ a smaller than usual income and health costs didnt allow immediate repair) here is the symptoms i've encountered; I recently changed the spark plugs and all 4 were oil covered(worn valve guide or piston rings?)The car ran great for two weeks and now the running symptoms have returned but not as bad. The running symptoms: engine stumbles on acceleration, with an occasional backfire. In addition to that, when I turned on the air conditioning the problem magnified by 3 or 4 times(fouled plugs, probs w/ fuel injection, clogged fuel filter, engine control system probs, intake manifold air leak, egr system malfunction, intake gasket sealing alignment.)Diagnostic test indicated misfire on cyl.#2. My question is this : are these symtoms and indicators caused by one problem or two, there are so many cross over symptoms that it has thrown me.
