Left Bank is running REAL LEAN after H/C Install....??? I just finished installing my ported LS1 heads and my TR224 cam, and now the car won't idle after it warms up and the left bank is showing real lean (on a snap on scanner). Ive replaced both primary O2 sensors, checked the intake and exhaust gaskets.....what else could it be????? any help would be GREATLY appreciated!

ok more info now.....its alternating between left and right banks. first one will be rich and the other lean, then it switches....i think im going to take it and have the PCM reflashed at the dealer.
