You might try getting some Marvel Mystery Oil an pulling the filter replace it. On the new filter fill it with the MMO , an install the filter an try running it -- AN NO IT WONT SMOKE !!

Scaning the truck while it running and check sensor inputs and watching outputs may help find your problem. (in reply to johnny5) Post #: 6

If the lights stays on when you start it bckup then id get scanned right away while light is still on. _____________________________ Nothing like 670 cubic inches of alcohol burning horsepower (in reply to cctxfish) Post #: 7
