Bought a 2001 Spyder a couple of months ago. Has Monkey Wrench headers and exhaust (too loud), no other modifications. Check engine light came on, the codes were PO446, PO440 and PO441 which are all EVAP related. The shop smoke tested then replaced the VSV and CCV.

I still smell gas, especially when the tank is full and the AC is on recirc. Took it back to the shop and they smoke tested it again and couldn't find anything. No apparent gas leaks.

Any ideas?

Roll down the windows when you fart and it should stop that problem.

To the OP, is the CEL still coming on? You may just have overflow residue from the tank still on it, I would give it a good washing with some engine cleaner and see if that does it.

Problem solved

Pack rats. They got into the hose that comes off of the top of the tank as well as the vent hose in case of the car turning over. So if you're in the southwest and are having odd EVAP issues, don't do what I did. I replaced all of the EVAP valves and the canister first, and then found out it was just a couple of very inexpensive hoses that were chewed through by pack rats.
