You only have 1 bank.

You might have a vacuum leak somewhere. I would check that first.

Usually with the car running spray all around the hoses and connections if the idle changes there is your leak.

Also check all the small hoses for cracks where it connects.

Carb or brake cleaner works best.

thanks, TECh.I found a loose small hose that goes under around the air box filter,I reset the code,how long does it usually take to come back,if that was not the problem to begin with.
