    Let me give a couple a try:

    (1) 1153 is insufficient switching bank 2, sensor 1 02.
    1416 won't hurt performance, probably a clogged passenger side secondary air check valve
    (2) Probably a symptom of the 1153 code?
    (4) Maybe piston slap, my car has done it since day 1
    (5) Check AC fuses/could be low on 134a and pressure switch keeping it off
    (6) That's the default setting for a vacuum leak, check the vacuum lines from behind the intake towards the check valve on the passenger side

    Hope this helps....

    The O2 sensor would be passenger side, pre cat. And would most definatly contribute to the poor performance, due to improper fuel metering.

    Sometimes it's easier to unbolt the metal air pipe from the exhaust manifold so you can remove the valve in a vice or on a bench. There's a gasket under it but most of the time it's reuseable. If it's messed up you can get them at a dealership GM PN 12553617 for a package and they're cheap.

    PCM Reset
    Turn key on, don't start car
    Pull PCM BATT and PCM IGN fuses in engine compartment
    Wait about 5 minutes
    Turn ignition off
    Replace fuses

    This will also reset all the emissions readiness tests and car will be a little grumpy until the idle relearns.

    No EGR tuning or code removal required on the '01 and '02 cars - didn't come with it from the factory.
