My "Check Fuel Cap" light came on after I changed my intake manifold. I can't find any missing or broken vacumme lines and I've removed and replaced my fuel cap several times...nothing has made the light turn off. I cleared it a couple time but i keeps coming back. I'm at a loss...
Sorry, it's a 2000 GT. I'll check the filler neck but the light never came on till I changed the intake manifold. Ill have to check to make sure the line is connected behind the fender. It is connected at the intake plenum. The fuel cap light has been on since the manifold was changed but I have never had a code come up.
