Is this something that turns on at 80,000 miles or could it be that I may have pulled the exhaust system apart a little due to high centering off road. I think I hear a small exhaust leak when decelerating.

All those lights come on when the check engine light comes on. You need to have your codes read and diagnosed. YOu can get codes read for free at autozone, but no diagnosis. Dealer will have to do that.

Maybe you ripped out an O2 sensor?

Thanks adam.

I still haven't fixed it but I have a question. When I stop/park my car, there is a vibration emanating from my gas cap. I assume it's "passing gas". Is this normal or could this be the source of the check engine light? I made sure the cap was tight and it still "farts"

No it is not normal.. Your gas cap is leaking.. It's actually pulling air in, not leaking out as engine manifold vacuum is used to pull a partial vacuum on the gas tank for emissions reasons.. You probably have error code PO440 set which is defined as follows:


Per the Factory Service Manual...
PO440 will be set when the fuel tank pressure is atmospheric pressure after the vehicle has been driven for 20 minutes.. (meaning air is leaking in and the system can't pull a vacuum on the tank..

Possible Trouble Areas:

Hose or tube cracked, holed, damaged or loose seal.
Fuel tank cap incorrectly installed
Fuel tank cap cracked or damaged.
Fuel tank cracked, holed or damaged.
Charcoal canister cracked, holed or damaged
Vapor pressure sensor
ECM

Thanks Dandeman

Mine just did the same thing at 85k. What did yours end up being? Just curious. I'm taking mine to Autozone tomorrow.
