    OP

    now that you have provided more accurate codes, assuming they are right, just "google" them for GM OBD1 codes....and 411 like this comes up which may give you a better understanding on what may be wrong.

    http://theimportkiller.com/forums/index.php?topic=420.0

    or any other GM OBD1 source for info

    A FSM (factory service manual) is very helpful if you are trying to diagnose or do the repair work yourself.....assuming you understand the procedures noted in a FSM

    also a recently replaced part does not necessarily mean:

    1. the new part is good
    2. it was installed correctly
    3. the wiring/connector "to the part" is be good

    18 is injector circuit. I just had this issue. I have an intermittent wire at injector 6 or 8. keep looking but to me sounds like your harness is jacked

    dude, really. map sensor will be a MAP SENSOR CODE, knock sensor will be a KNOCK SENSOR CODE. SEPARATE CODES. NOT THE SAME. ONE WILL NOT CAUSE THE OTHER.
