Please help. Engine codes after spark plug change
Hey guys, I replaced my spark plugs (with the same factory plugs) earlier today and now I'm getting two engine codes (P0033 and P0034) and it's running like crap. I did have to remove the circuit box under the hood to gain access and forgot to disconnect the battery first. Not sure if that has anything to do with my issue? I do have a custom tune and I'm really hoping that removing that circuit board didn't wipe it out?
Please advise. Thanks!

Just disconnected the battery for 20 minutes and rechecked all of the hoses and circuit board under the hood. The light is now off and it's running perfect. Whew!
I did think it was interesting that the DIC had me run both of the power windows down (separately) and then up again. Once I did this and checked the "ok/check" button, it didn't come back on. Seems odd.
