Oil Pressure Pegged...
Well, like the title says, I got in the car this evening to go pick up a relative and as I was letting the car warm up I noticed that the oil pressure guage was pegged. DIC showed oil pressure was 130. 
I turned the car off and then turn the key to the on position but didnt start it. There the guage was still pegged and the DIC was reading like 113 or 114.
Did I just have a sensor go bad
or is there something else I should be worried about?
I read about the faulty guage and think this is probably the problem anything else I need to look out for?
Any help would be greatly appreciated...
Merry Christmas... I hope Santa was good to all of you! He brought me a book on 50th Anniversary book on Corvettes that gives a ton of history and specs on all generations of corvette through the C5.
Thanks
Jason

Your car is fine.
The pressure is fine
Your oil is fine.
Your car is safe to drive.
Your oil pressure sensor, however, has seen better days. Mine also told me of 130 lbs pressure - but it was just dead.
Your oil pressure sensor has fought the good fight and has moved on.
Sadly, GM apparently decided to posite this sensor within the intake manifold. Installation of a super-charger will make replacement of the sensor less of a consequence.
Good luck - and Merry Christmas,

I'm still trying to figure out the best mod for the buck. Then its time to replace mine too. Heck, I'm starting to think 130 psi is normal for these cars.

Oil sensor fix
Remove the coil covers, the air bridge, and the wires connecting to the injectors. you do not have to disconnect the fuel line.. remove the bolts holding down the intake... lift and move forward about six inches... the sensor is located about an inch from center towards the drivers side... remove the connector .... ( make sure you cover the two open intake chambers with a towel so no dirt gets in there) ... you can reuse the intake gaskets.,. remove the sensor ( 1 1/16th socket ) ... put in the new one.... torque to 15 ft lbs. ......... intake bolt torque 1st pass 44 in. lbs., second pass 89 in. lbs. Also ( very important ) there is a 1/8 black vacuum hose which becomes disconnected when you move the intake forward.. it is located about two inches from center on the passengers side up under the window cowl.. it connects to a rubber "L" shaped connector almost in the rear center of the intake.. this vacuum line controls your A/c doors... Here is a picture of the sensor location.... I hope this helps..

Ok, so today I enlisted the help of my buddy pyro5o and we replaced my oil pressure sensor. Phew... Actually thanks to the instructions I found on the forum it was not to bad. Probably took me a lot longer than it would have taken anybody else, but I dont know much about motors... Took about 3 1/2 to 4 hours, but we had to make a run to the discount auto parts store twice...
Felt pretty darn good working on this thing myself rather than taking it to the shop. This could be trouble...
Thanks again pyro5o for all your help as well as your tools...
If anybody is considering doing the this, the hardest part for us was re-connecting the tiny little hose at the back of the intake that looks like a swizzle stick. Real PITA to re-connect. Other than that, not bad at all...

The AC Delco part number #12562230 is no longer valid (shown in the above photo). PACE states there is a similar sensor called "Sensor E" with a part number of #12573107
Is this the same part? Will this work as a replacement for this problem?
Thanks
Michael

The part that I got was not AC Delco, it was GP Sorensen and is called an oil pressure switch. Part #OPS191...
The only other things you will need are a gm fuel line removal tool and a 1 1/16th deep socket. The only other problem was the small vacuum line at the back of the intake that will disconnect when you take out the intake. It is a PITA to reconnect...
Hope this helps...
