Had a bad PCM and I replaced it. Fixed a LOT of problems but still having loping at idle (not the good loping of a performance engine), stalling sometimes, sputtering sometimes, black smoke when you floor it. Codes come back 565 Canister purge valve circuit fault.

I've watched videos and read through forums and cannot find a canister purge valve on MY truck. On other posts of people with similar problems some have said maybe it was removed, maybe it didn't have one and my PCM is looking for something that isn't there, but I haven't found a definitive answer.

Any help is greatly appreciated.
