I pulled the plug last night and it looked old and out of gap, it had some oil on it but no antifreeze smell. Could it be taht I have a leak in the cooling system, and the misfire is something unrelated. The pkugs were autolites and I heard on hear that they suck. Also the coil packs are original, so maybe this is part of the problem. One more thing, when I pulled the plug I put in a bosch platinum that was brand new, and I took it for a quick spin, once I sat idle for a couple minutes the CEL started flashing, took it home and parked it.
I don't want to throw parts and money at it untill I know for sure whats wrong. I think I'm just going to take it to a dealership and get an estimate. If it is head gaskets, would I be better off puting in a new Jasper engine, as It has a 75,000 mile warranty, plus it's NEW! Please help!! Anyone else replace head gaskets? how much?
