Sure thing.

The charcoal canister is located upside-down, behind the RH rear wheel, above the black plastic access cover. Note that this cover is not present in the equivalent location on the LH rear wheelwell area, so it should be obvious where the correct location is on the RH side. After removing the access cover, there's a friction type strap around the canister which can be loosened with a flat-bladed screwdriver, there's 2 spring hose clamps to remove, and there's 2 plastic clips over the "top" of the canister which is actually the part closest to the ground in this case. incidentally, it's this upside-down mounting that makes failure of the canister particularly likely to cause the dissemination of charcoal particles.

GM PN for the canister is: 17090139
I purchased an aftermarket (Standard Motor Products) CP1031 for a few bucks less.

UPDATE: The Standard Motor Products canister is the OEM Rochester unit, with a GM part number on it.

Replacement of the purge valve is only needed if you find charcoal particles in the lines. it's located under the plenum, just aft of the 2 large breather hoses. It's secured by 2 - 8mm bolts.

The purge valve PN is 01997201 for ACDelco. Note that the new valve does NOT come with the bracket, you must save and reuse your original.
