My car does that every six months or so with a similar error and I go get a new gas cap (or tighten it in some cases) and it just goes away. Quote Need an install?

ryde2idie Posted March 25, 2009 Report Share Posted March 25, 2009 (edited) your exhaust could have a leak somewhere (probly close to the head) allowing oxygen to suck in at idle speeds. Edited March 25, 2009 by ryde2idie Quote Quote Link to comment Share on other sites More sharing options...
