#1 of 1 2000 Emission problem
Oct 14, 2009 (12:13 pm)
The "check engine" light comes on and the code indicates a problem with the vapor system. Gas cap is good and the problem will go away at times for 400 or 500 miles and then the light comes back on.
I was wondering what others have found to be the cause if they have experienced problems with vapor system. Thank you in advance!
