Have a question.

Like 2 months ago the service engine soon light came on and it was running real rough we brought it to Autozone and they said it was a miss firing engine in other words it needed a tune up. Well, we put in new spark plugs and wires... one of the plugs that came out of it was dripping with oil (it's like the first spark plug on the drivers side on a '99 Mistsubishi Eclipse RS.) Was hoping it would clear up on it's own, but I think it's too much oil to do that. Anyways, we just got back from South Carolina to visit family it happened again service engine soon light came on and we already knew it was the same spark plug again and sure enough it was the problem dripping with oil again and it's that one spark plug. I was just curious has anyone else has experienced this same problem with their Mitsubishi and how much did you pay to have the problem fixed? Thinking about putting it in the shop to have it worked on when income taxes come back and considering it only having 71k miles on the car it's worth to fixing it in my eyes.

Thanks for reading.
