    after looking for 4 hours, i found a leak in my 02 sensor in my test pipes. The passanger side. that was what was throwing the CEL and causing a loss of power. The engine was getting less gas because it was not sensing all the air.

If anyone knows maybe why its not boosting correctly or has any ideas i'd greatly appreciate any information. Thanks
    P0420:Rear O2 sensor.Either it's taking a crap,loose or your wiring is damaged/unhooked.32 bit ECU's rely on the rear sensor more than the 16bit ones so they might have more of a hissy fit when you have a problem with it.
