After the car warms up the gauges (oil pressure, gas, boost, info center) start jumping peg to peg! Checked both ground buses and they were clean and in good shape. I checked the battery cables and they were tight and clean. I am afraid that the gauges will get damaged if I let it go on!
Any help would be greatly appreciated.

My 95 did this for years before I finally got sick of the gauge dance.

Your instrument cluster may have internal corrosion on the connector pins for the two boards inside of it. This corrosion will cause the symptoms your describing.

Two possible fixes here for the right three gauges. oil pressure, boost, temp.....

First is to take apart your gauge cluster/instrument cluster and pop off the right three gauge pod and clean the connections. Works most of the time. Just apply dielectric grease before putting it back together though.

Second would be to find another gauge cluster at your local salvage yard and swap out the right three gauge pod.

I tried the first step until it failed again so the final fix was option two. Which has now lasted for 4 years with no problems at all!

If your patient and careful, taking apart the instrument cluster is not hard at all. And while your at it take off the larger gauge pod and clean those connections as well. Look for corrosion on the little connector pins. And use steel wool to clean and shine up the connector pins. But be careful to not damage any solder on the board. When your finished apply the dielectric grease as mentioned.

Thanks for that info Todd, I have the same issue.

Just curious do you know if anyone has a write up done for taking out the cluster?
