Now for the check engine light. The scanner code is "P0442". It also said that it was an "emissions leak". So I am guessing that its refering to the "evaporated emissions leak" deal where it could be several things, one of them being the "loose gas cap".
I have cleared the code, and checked the gas cap and for now, all is well.

Thanks for the help everyone.

90 times out of 100, p0442 is because of a evap canister vent solenoid. I musta replaced 855493 of them at work. ALSO if you are in the habbit of over fueling the truck. It will saturate the evap canister too and if thats the case replace the charcoal canister and vent solenolid. its not the gas cap... if it was a faulty or loose cap you would get a p0440 code....trust me....

Thanks for the info Spudz!

We haven't been overfilling the tank...it's hard enough to keep a half tank in a suburban!
Not to say that the PO didnt overfill it. We have had the burb for almost a year now, so I am learning about the truck as problems arise.

So far the light hasn't come back on, but then again, its only been a few days.

Do you have the GM part #'s for the solenoid and canister handy? Not a big deal if you don't.
