And misfire is back. P0303 all over again. I checked the oil and it was bone dry so changed the oil and pulled the plug. Plug was fouled up real good. So I put in a new plug, used mobil1 HM 0w20, and cleared the code. Drove it for a few miles yesterday and thought so far so good. Wife goes to take the kiddo to school today and the code popped again. It almost looks like oil is getting in the area where the spark plug electrode is. The threads are all bone dry right up to the electrode.
Any ideas?
