Answers :

Anybody tried rubbing a sticky substance on the "O" ring of the cap? I don't care if it's a candy from a kid, it's worth a try. Clean threads of filler with alcohol real good before too. I'd try taking the cap off, and roughing the threads up with rough sandpaper too, just to give it more bite. Blow threads off good after.

P2176 code my wife went to start the envoy this morning and it started but when she tried to back out the envoy was very sluggish and would hardly move. The engine light came on and she just left it there for the day. When I came home I noticed the gas cap was very loose . I tightened it and drove it around the block with no apparent trouble. I checked the error code and it said P2176. Is the gas cap the problem ?


NO , gas cap not the issue here . the P2176 refers to throttle actuator control system - idle position not learned .... the test for this is a mile long , i would try clearing the code , and see if it returns , or it will reset itself if it see's 3 d ... 2004 GMC Envoy

My 2005 Chevy Cobalt began showing a "Reduced Engine Power" message, then a "Engine Disabled" message and completely stops. I found that the gas cap was loose and tightening it allowed the car to start. The check engine light would stay on for a while afterward, but eventually goes out. Today it stopped 3 times in one 3 mile trip and every time, the gas cap had loosened again. Does this sound like a gas cap issue, or is that just a coincidence?


The gas cap being loose causes a vacuum issue in newer vehicle which causes your other problems. The issue of the cap coming lose is most likely a bad cap. Replace it and that should solve all the problems. ... 2005 Chevrolet Cobalt

I sometimes find that my gas cap is hard to maneuver but eventually it'll loosen up after I pull up on the gas release lever. I lent my car to my BF's brother...needless to say they took pliers to the gas cap, and broke it. :( Now, he wants to come home and try to pull the rest of it out. The thing that really sucks is that I love my car, but this problem is ridiculous. I'm just happy it happened when they were tinkering with it, instead of me- Lord knows I would never hear the end of it.Is ther

2004 GMC Envoy, My service engine soon light came on. I took the vehicle to a mechanic and the code came back po422. A smoke check was performed and they said it had a leak in the filler neck and the entire gas tank needed to be replaced. So the dealer replaced the tank and now I'm getting a loose gas cap message light on the dash. Since the dealer did not replace the cap when replacing the tank is that what the problem is, or was it not the gas tank issue at all?


Hello: Without being there when the smoke test was performed no one can say what the results of the smoke test were. I would go back to the dealer and speak to the service director/service manager and request a new gas cap. ... 2004 GMC Envoy
