    My engine light was on and I checked the gas cap. It was not screwing on prperly and would pull right off. The engine light turned off as soon as I replaced it and started to drive off.

    BAD FAN CLUTCH! I've had this problem twice. First time at around 60,000 miles. Now again at 228,000 miles. I realize that at 228,000 miles things are going to need replaced or repaired from time to time, but it seems that all of the repairs that I have had to make are repeats of things that I have already repaired peviously. The fan clutch, rotors, linkage, tail-lights & I'm on my third new gas cap. Not to mention that Ozzy Osbourne has been held hostage in the CD player for the last three years! LOL! Actually, I feel like I can't complain too much because given all the miles I've put on my car for the most part it has been a very reliable car. It's never left me stranded anywhere **fingers crossed** and has never felt the cold cruel hook of a tow truck. I will drive it until it falls apart around me because I LOVE IT!

    The check engine light started coming on and I had heard that it could be a problem with the fuel cap. I tried tightening it up when I fueled up and this helped for awhile. Now it stays loose and the light stays on, guess it is the firt vehicle that I've ever owned that had a sensor in the gas cap or a gas cap that didn't fit right. I also found out that this will cause the fuel gauge to work crazy, too.

    So the tighten fuel cap warning came on in the window where the odometer usually reads, went off in a few minutes. The next day this happened again and then the engine light came on later. Test at the dealership showed leak, recapped the gas tank, dealership cleared the code and it was fine. Until two days later the light came on again and the same dealership tested it and found an EVAP code again and the fix would be to replace the purge valve because it was staying open. $200 later and the engine light is on again. Ugh! Tired of putting so much cash into this 8 year old car...

    Check engine light comes on and off. I have changed the gas cap, and that works for a while then starts up again, cap becomes loose.
