ramheaddodge98 Posted July 13, 2009 Report Share Posted July 13, 2009 Have an 03 SSS, check engine light keeps coming on. Go to pull the codes and comes back with EVAP Emissions Leak, Large, and theres always 2 codes. Ill delete them and drive it some more and the light comes back on. Same thing, sometimes it stays off 2 days, sometime 2 weeks. Many people told me try a gas cap, thinkin it was a cheap fix i tried it and did not work. Any suggestions??

12'SROCK Posted July 13, 2009 Report Share Posted July 13, 2009 what are the actual codes? Quote Link to comment Share on other sites More sharing options...
chpspecial Posted July 13, 2009 Report Share Posted July 13, 2009 It must either be the flux capacitor or the muffler bearings. Have you checked those out Quote Link to comment Share on other sites More sharing options...

Fireman31 Posted July 13, 2009 Report Share Posted July 13, 2009 My guess is that he is throwing a P0449 which is a EVAP canister vent solenoid valve malfunction, and a P0455, which signifies a massive EVAP leak. This issue is common, the vent solenoid valve most likely needs to be replaced..... Quote Link to comment Share on other sites More sharing options...
