Cars throwing a few codes... It throws a o2 high voltage bank 2 sensor 2. o2 low voltage bank 2 sensor 1. and cylinder 6 missfire detected. I know before my EGR seal inside the intake was screwed up but i placed it correctly. Could that possibiliy be throwing the o2 codes? also what could cause the cylinder 6 misfire? this is very annoying to me. and dont know were to start....

 

For the misfire problems I would start by checking wires, plugs, then coils for starters.

As far as the O2 sensor codes, it could be a number of things. Do you have headers or have you changed the exhaust at all? I would start there by cleaning the MAF, then replacing the O2 sensors if that doesnt do anything.
