I knew that I should put a disclaimer in there, as the 2000+ are different in a number of ways from the '96-99. Let'* face it, we're all more familiar with the year/years we own...

From a PM from Dave...he swapped gas caps with his GTP buddy and the issue still persisted on the Bonneville. In other words the gas cap was informally tested and passed.

The Dealer claims they checked the fuel filter and did a pressure check on the lines and everything checked fine, but I will check them again myself.

I think I just solved the problem.
Found a connection on the canister that wasn't snug.
It pushed in about 1/2 inch and clicked.
Reset my codes.
Thanks all.
I intend to visit the dealer and ask them for my money back tomorrow.
