I just pulled these codes......car is very bogged down with small backfires......If I give it a lot of gas, i helps clear it up......wondering what the codes are....



P0300 Random Multiple Misfire

P0410 Secondary air injection Malf

P0412 System Valve Malfunction
P0152 O2 Bank 2 sens 1 (I've had this one)

I would need to scan the car and replace the 02's. Im pretty sure that would take care of the problem.

The air codes shouldn't affect performance (if you still have air check the AIR PUMP fuse under the hood). I'd concentrate on the precat passenger side 02 sensor, might take care of P0300 too.
