After getting my car out of storage I noticed it has been running alittle rough, not all the time though! Some days it runs just fine other days it runs real rough, others it runs rough for a while and goes to running fine again! I work at a car dealer ship so I used the scan tool to get the codes and this is what I came up with!

Slow codes:
85- adpative lean limit reached
85-Canister purge failure
31-EVP/PFE volt lower than minimum volt
63-TP circuit lower than minimum volt

Codes pulled when car was running
21- ECT higher or lower than expected
44- Air injection system inoperative bank #1
94- Air injection system inoperative bank #2
13- Cannot controll RPM, Low RPM check

I know some codes are from some of the mods that have been done to my car, but am not sure if any of these codes are any to worry about! Can any one help me figure these codes out or point me to some one or some where that can help!
