    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.

    The newer gas caps do not fit properly on the older Envoys creating a problem of the check engine light not staying off.....I'm on #4 and check engine light is still on!
