check engine light

[95allen]

My check engine light won't go off and I'm not having any problems
with my jeep will this keep me from passing my emission test and is there any way i can get it to go off.
so I can pass the test.

I just had that problem with my jeep..I changed the gas cap back to the original cap and it solved my problem. I had bought a locking gas cap with the key, but had to take it off to get that fixed.

The guys at Autozone will read the code for you (usually for free). I wouldn't just start changing parts. That can be an expensive crap shoot. Get the code read and post an update. Hopefully it is just the cap not holding pressure. :-)

p.s. if it is a faulty gas cap, for the love of god don't BUY a new gas cap. Go to the closest gas station and tell them you might have left your cap there. Typically they have a box full of them behind the counter. Find one that fits and your all set. Cost = $0.00 and besides once the box gets full they start to chuck the older ones anyway.
