OK..thanks for the advice.
I hate to say it but I have not changed the plugs the whole time I have owned it (2nd owner, bought it with 42,000 miles). It now has 114,00 miles. The plugs I just pulled looked bad...surprised it still ran, and they were Champion plugs. Put in new NGK's.
It dose seem to run a little smoother...time will tell.
Thanks all!
Peace
