My car is a 1990 Mercury Cougar XR7 SC, 5 speed, 135,000 miles.
I have a problem that seems to be stumping my local mechanic. I have two plugs that have become oil fouled #1 and #6. He has done a compression test and a flow test. The engine he says is fine and not the problem. The engine is very new (April 2004) and they cleaned up everything real pretty when they put the new motor in. All the sensors were checked and the injectors were cleaned too. It was running great for a couple of weeks. I've replaced the plugs and the car runs great now but I'm wondering what could have caused it and it will probably be just a matter of time until they become fouled again. Any suggestions on what to check??
