Have you ever cleaned the mass air flow sensor?

I'd check for vacuum leaks fisrt and then go and either swap the sensors from the two banks or just buy another one and change it and see if it stops the problem.

I bet you didn't save any of the old sensors when you changed them, did ya, lol? I changed the plug wires in my pickup a couple years ago and one is shorted already. And no, I didn't save any of the old ones as spares.

Already check checked for vacuum leak on leak and yes i saved 3 only got rid of the 1 that failed. I allways have a spear set of plug wires. Had to learn that lesson the hard way also.
