Question Asked: Replacing the gas cap
April 01, 2011, 06:24 AM
A couple of months ago my check engine light came on and my indicator warning periodically will flash check gas cap. I read the post about the loose gas caps so I bought a new one, but the light never went off and the indicator warning still flashes sometimes. I took the van to auto zone and had them run the codes and it came back with P0449 and P0455. Can you tell me what I should do?
