Rooster2 Posted August 22, 2014 Share Posted August 22, 2014 Just came from an auto parts store that pulled my CEL code. Result came back PO 440 code. This seems to return weeks after I fix something. I have replaced the gas cap, and fuel fill pipe going to the gas tank. Any suggestions of what else I should investigate to fix and clear the code.

Rooster2 Posted August 23, 2014 Author Share Posted August 23, 2014 Well, maybe I fixed the CEL code. I swapped gas caps with my wife's 98 OBW, and CEL light turned off. Even a relatively new gas cap may not seal that well. 1 Link to comment Share on other sites More sharing options...
