    What do these Trouble Codes mean?! 22, 33, 35, 44, 45.

    So, I am getting these Codes from my '91 Oldsmobile Cutlass Supreme 3.1L V6: 22, 33, 35, 44, 45.

    What do these mean?
    Where can I get a list of what these OBD-I codes mean?
    And most importantly, how do I get my car working again?

    Here are my symptoms:
    - car starts very rough and only if I hold down the gas pedal for 5+ seconds
    - car runs at high RPMs, then low RPMs(as if it is going to die, and does die most of the time unless I keep pressing down on the gas pedal at least a little)
    - performs great while accelerating, but wants to die when idling at a stop light or stop sign
    - BONUS: sometimes my car dies while coasting(not accelerating) on the free way traveling at 30mph

    Other Notes:
    - I just replaced the EGR Valve and cleaned out the carbon deposits from the port
    - I just replaced what I think is the Vacuum Hose

    Thanks for your help,
    Darryl

    How do I check the MAP sensor?

    If you can get it to idle, tap the sensor firmly while it's running and see if it makes a difference. Also check for cracks in the housing, as well as the vacuum line fitting on the bottom of it.

    A bad MAP could cause that cause the engine has no other way of monitoring air flow into the engine, Therefore not knowing how much fuel to dump

    So, if I replace the MAP sensor things should get a lot better?

    Sounds like it! You may have to relearn your idle as well but I'm not sure....

    This is after you replace the MAP, that is.

    Hmm, you're right that doesn't make sense. Maybe I miss read the blinking Check Engine Light. Maybe I am supposed to only have read 45, not 44 and 45.
