Oil pressure high...

After my last two oil changes my oil pressure has been through the roof. Im running about 130 psi...is this going to hurt my engine? What can I do to fix that?

Wow, 130?
I'm not sure, but could it be that your replacement filter has some sort of restriction in it, like maybe the wrong size, or they forgot to take it out of the box?

Do you show oil pressure with the key in the on position and the engine off?
If so, you have a bad oil sending unit. Very common problem

You have to pull intake to replace the oil pressure sending unit. I just had mine done under extended warranty.

Heh, my dealership thought it was the gauges! Then again these are the same guys that don't have a clue how to use a torque wrench....I know from experience.

Listen to the guys here, it's the sender. You can get it from Fred Beans or Gmpartsdirect.com for around $30....or from the dealership for ~$60.
