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.
