Gas Cap
Yesterday I got into the car to go to work and when I start my car, the display screen says "Check Fuel Cap". So I get out, go to the back, and check the cap. It was loose. No big deal. I screw it into place and hit the reset button. I'm about halfway to work and the **** warning comes on again. I go all the way to work and park, then I check the cap... its tight! So this happens again when I go to start the car to come home and it keeps throwing the warning. Last night when I finally got home I undid the cap and checked it. No scratches, no cracks, the rubber ring around the top is not discolored or dented or torn or anything that would normally show a faulty ring.
So I'm completely baffled about this and was wondering if anyone had any ideas besides buying a new gas cap. And do I buy an aftermarket one or do I go to a dealership to get one?

I had the same thing go on with my 2001 Intrepid. all I had to do was remove the cap and put it back on. It was like there was a vaccuum or somrthing that would trigger that check engine light.

I did that several times. Unscrewed it, removed it, then screwed it back in and restarted the car. It still keeps doing it. And I noticed the filler neck moves a bit when I push on it. I'm sure I'm just beign paranoid now. lol.

you'll need a new gas cap. you can probably get one from an auto parts store, which should do the trick, though I'd probably go for OEM replacement, just to be certain

If I remember right, it takes several drive cycles for the message to go away. Keep driving it for a week, and if it doesn't go away after that, then look into a different cap.

It was accidently posted in the wrong forum. Completely my fault and I ask any mod that sees this to move it. I apologize guys.
And theedge67, it did go away as it cycled itself out.

Glad it worked itself out. I don't know why those sensors take a few cycles to reset, to me that is stupid. Why not just show the light when it is a problem, and as soon as it is not a problem, the light turns off? That would make sense though, so they couldn't do that....

Getting one in my 1998 GT. Gas cap is fine. Just replaced the fuel pump with a high volume pump, the filler neck seal and a sensor on the top of the tank. I don't know where to begin. Any way to run a pressure check and find the leak? I did bend one of the plastic hoses going to some external component that has to be an emissions gadget when reinstalling the tank. But it doesn't look cracked. There is a rubber hose adjacent the filler neck that looks pretty tired...maybe I'm answering my own questions. Any help appreciated.
