Mine is doing the same as stambo58 I have check all the wiring to the TAC, APP, and from the ecm. I have checked the TAC cleaned also replaced TAC & APP with no prevail. I started out with a p0410 secondary air valve fixed that then a week later a code p2101 popped up I am a mechanic by trade and I am getting really stumped on this one. Oh yeah I pulled the upstream O2 sensor to see if the cat was clogged ran it still no difference.
