P1415 shows air system 1 fault
If either of these codes came up followed by an "H" then it was probably just a momentary fault, if either of these is followed by an "HC" then they are a current fault. I would try to reset them by going into manual diagnostics and pressing the reset when the DIC displays "PCM-2 codes" then see if they repeat.
If they happen to repeat then I'd have to take a guess and say that the check valve on the left exhaust manifold is stuck. the way the air system works is when you first start your car when it's cold the air pump will kick on for a minute or so and pump fresh air into the exhaust system if the oxygen sensors see this the voltage changes, then after a minute or so the air pump kicks off and the system switches to closed loop and the oxygen sensors control the AFR.

I went ahead and cleared the codes to see if it comes back if it doesnt im not gonna worry about it if it does im gonna order the check valve. I guess if that doesnt fix it ill buy the O2 sensor hopefully it will be ok. Thanks for the help.
