    Not trying to be a dick, but oil gauge reads pressure (L - H). The fix for this is likely the stepper motor which can be done yourself with a little soldering skill. Do a quick search on stepper motor and you will find some threads that discuss how to change it.

    Not 100% sure what your talking about.. but sometimes the pins in the cluster get knocked outta whack, and need reset!...I would look into it a little more before paying that much when it could be a very simple fix!

    He is talking about the stepper motors that work the guage needles(they can fail and peg the guage at crazy readings I have seen it happen myself on my dads h2(speedo read 45 when going 20)

    It is more likely the oil pressure gauge "Sender" lacated at the rear, top of the cylinder block. I've had several GM vehicle do the same. The sender is hard to reach but can be done. It's also less than $100 for a dealer to do.

    Yes sender is on the back drivers side on top. You just need a deep socket thin wall socket ( can't remember size sorry) I got the sending unit at rock auto it was like $40 15 min job just did it a month ago.

    Mine just acted up. Mine stays around 70 psi with the ignition off. Stepper motor? Where is the stepper motor? Is it part of the Instrument Panel Cluster?

    It is part of the cluster and is replaceable
    I advise doing all of them since one is acting up

    Where would I get the stepper motors? Dealer part? Radio Shack?
