Just recently my Check Engine light has come on and Ive been getting the codes P0410, P0412, and P0418. Ive cleared the code but they come back after a couple minutes of driving. Does anyone know what the problem might be and what to do to possibly fix it, any help is greatly appreciated.

i had those codes come up on my 2001 WS6 Trans Am. My problem was i had removed the air pump with all the tubing and blocked the EGRs since i had Long tube headers. i guess when i had it tuned they didn't removed that code. But i installed my air pump and all the tubing and connected the EGR tubes back, i reseted my computer and the codes never came back. so unless you've removed ur air pump i suggest u put it back.
