Thanks again for your help everybody. Tried the Marvel Mystery oil. Still having the same problem though. Every once in a while as I start to accelerate, the enging kind of bucks and hesitates. It through the CEL on again. I have to believe it's the same code as before. The shop out here really is at a loss. I decided to take it back down to the city where I used to get my work done at. I have an appointment for Tuesday morning so we'll see what they say. What a way to stsrt the New Year. BTW, the hot water tank in the house went out yesterday,I hope the whole year isn't going to be this bad...
Happy New Year everybody.....
