Engine light/ gas cap ?
Ok, the first time many miles ago I put my engine light out by tightening the cap and driving though a half tank of fuel. Now my lamp has been on for some time and I'm not sure if my gas cap is even tightening properly. Does anyone think I should just replace the $26 cap, hope it works, and call it a day. I have very little time available to bring the car in for diagnostics.

I would check for codes. Most auto parts stores will do it with no charge. A check engine light will set a code. If it's the cap it usually will say check gas cap or something like that. (I think) Maybe somebody will help on that.

My gas cap message came on awhile ago, first time I took it to the dealer and they replaced the cap free of charge. Same thing happened about 6 months later, greased it, tightened it, loosened it, tried everything and the message stayed on. I went to the local auto parts store and bought a $19 Stant cap (don't remember the number, non locking though), message went out next day, end of problem and almost a year later still no problems.
