Check Eng. & Ckeck oil flicker

They flicker on and off as they feel like. The dealer told me it was a chip in the dash at $300. Not sure what chip needs to me fixed. We did get 2 insterment cluster from the junk yard. One was repaired but couldn't see what.

My '92 has done that since it was new. My '77 Olds also had a problem,, since it was new, until I found the bad ground.

I know that the Dealership *said* they fixed/replaced stuff at least 3 times. I figured it was another classic Olds sucks at wiring problem.

If you find out what it is, let me know!
