The code is related to a massive vapor leak in the system. I first replaced the obvious: gas cap. No difference. The vapor smell is coming from a series of fill tube lines that go to 2 different valves and a shoebox sized canister (I assume Charcoal) under the trunk floorboard. There are other lines going toward the front but the vapor smell is strongest at the fill tube area just behind the rear wheel.

I did an OHM check on the coils and got 24k UF and a 13 volt signal to both connectors for those valves which to me, rules out electrical. I then dropped the canister to see if there's anything obviously wrong but to no avail.

Anyone else have this issue?

As Bobby stated, it might be you filler neck. Take the wheel off and remove the black plastic cover, beware of the crud that will fall. Visually inspect the filler neck for rust. My XT currently has this issue. Today I purchased the parts to fix the problem from Jackie.
