Last night got the ty back from a shop who tuned it. It ran harder than it ever has. then I let it rest for the night. Got in this morning and it was stumbling, hesitating, and idle was real bad. It even died on me just idling. Anyhow the codes I pulled were 21, 31, 34. Where do I start checking?

no kidding!
clear the codes by disconnecting the battery. Check basic stuff, such as loose wires, burnt wires, plugs....basics first! chip seated properly in ECM. etc.

well for a while i couldn't figure out what was going on. so i had a shop look at it and they said i had some bad electrical problems. fixed that and re-programed my apex-i avc-r. after that it ran amazing. but then the other day i jumped in and it ran real bad.
