well the light that came on was not due to this I do not believe..... the code that came up was p1457 which is something in the evaporation system related..... and the fact that I never hear a pressure sound when i open the fuel cap could be another problem... the thing thats weird though is that the code only comes on randomly and stays off for a while once I clear it.... some people suggested it could be the purge or purge valve since that is what builds up the pressure in the gas tank....or that I could have a leak somewhere.... but its not leaking gas whatsoever
