So once and a while right after I bury the peddle "WOT" my "CHECK GAUGES" Light comes on for a few seconds then goes off. It's only at "WOT" never during normal DD. Like I said, it doesn't happen all the time just every so often...

Are you low on oil causing it to slosh in the pan starving the pump and your oil pressure drops? When it tells you to check your gauges have you noticed anything out of the ordinary?

Oil is perfect...in fact I just changed it out a few days ago. And nothing out of the ordinary when it happens.

When I hit it WOT the OP Gauge is sitting well above the half line. I have a new Melling pump and pick up tube w/ stock pan. I did notice that after a oil change it still seems about a quart low?? I thought they only called for 5 quarts??

Just like they said, watch the oil pressure, may be sloshing around...I lose about 1/4 of a tank when I step on the brakes! lol
Riddle me this;
Mine does the exact opposite, only under cruising, totally normal DD.
Will come on for 10-15 min, go off, or stay off if I turn the car off.
Do our cars hold a history for the codes so I can check what is happening even if the light isn't on?

Mine has been doing same thing only maybe more than yours. I have tested and checked ,oil pressure (over 60# wot) alt. battery,temp,& gas cap all ok. I talked with 3 gm service managers all thinking its the IP CLUSTER itself. Just going to keep watching everything for now & take it out later.

Lol I will bang away...I hope it's not off. Is there a way to better secure the pick up tube if it did fall off?

i just came across this thread on a search for something else...
i had this problem awhile back, at high rpm when shifting the check guages light would come on briefly. then after awhile it started blowing my ignition fuse. the fuse would blow, the guages would stop working, and the car wouldnt start after shutting it off.
time passed and it started blowing the fuse the instant i would turn the key on...
it ended up being a wire under the console shorting out against a bracket that was chafing the wire. if you take the console out it was a blue wire (iirc) running from the computer under the console routed along the right side of the shifter and going into a loom right behind the metal bracket the console attaches to up front. that metal bracket was what the wire was shorting against. pretty much the area right behind the cig lighter on a firebird.
not saying this is your problem, but it was mine. certainly a bitch to figure out.

I have a 97 Z28 and it started doing the same thing to mine after i hit 160 on the freeway smoking a skyline. but mine doesnt stay on. it just blink rapidly when im on WOT at high RPM's. I dont know what the problem is either.
