Engine light on, fuel cap light comes on after five miles of driving. Plug-in testing reveals unidentified vacuum leak. New cap for 30 bucks does not restore the loss of faith in a part that should last longer than five years.
Check engine light will randomly come on...not just after filling up. Eventually goes off. Took to shop and they said it was the gas cap. They messed with cap and light went off. About an hour later the light comes on again. Grrr.
