went to change my spark plugs today and found oil all over the number 5 n 6 spark plugs. The cars been runnin like crap it wont rev over 4500. It stuters when i try to move it like its running out of gas i checked the timming its spot on. i tested every thing from the coils to fuel pump and its all good. theres no oil in the spark plug valley. so im wondering if its valve stem seals or rings.
