Hi everyone. Still new to this website. I have a 1992 dodge w250 and the gauges are all out of whack. My oil pressure is high, my temperature is high, when I hit bumps on my road the speedometer drops and then goes up again. Just wondering if this has anything to do with the sending units or is it the gauge cluster? Any help would be greatly appreciated.

Thanks in advance, Braden

Check your Ground's first and then double check the wiring going to trans maybe you have a wire shorting out

Second vote on gauge cluster grounding and connector.

My speedo did that the last couple bumps I hit before my front clip body grounds all melted.

As for the speedo bouncing around, mine did the same thing. Got under there and looked and found the VSS was damaged from the previous owner not being mechanically inclined. Bought a new one from rock auto for 10-30 bucks and put it on. Works better than new. Not a hard part to change at all
