Re: check engine light 850 1996

DO NOT TAKE IT TO A DEALER unless you do the following....

drive the gas tank dry... meaning, leaving about 15 miles left in the tank. Then fill up with high-grade gas. Put the gas cap on TIGHT. Drive it around for a few. If the light doesn't go out, THEN take it to a dealer. If you look into the brickboard archives, you'll see MANY articles on this. It's happened to me!!!

This was the quickest/cheapest fix I've yet to do!!!

The problem comes from the gas cap not being as tight as it should. I guess air gets in or something and messes with the O2 sensor. I'm probably wrong a bout the O2, but I'm sure about the tighter cap... Do it, you have nothing to lose!!!
