Hello all,
Just a quick question. What would cause my OPG to all of a sudden start going crazy? At idle it goes nuts but apply the throttle and it does what it's supposed to do.
Thanks,
Kevin

Check the wires going to your oil pressure sender - maybe they are loose or possible the sender is going bad. Just a thought.

I agree with Kevin. The harness connection to the pressure sender is upside down. There should be a plastic clip to keep it in place. I'll bet donuts to dollars that that 15+ year old plastic is long gone. Since the connector is upside down it can get a bit loose and/or the connectors can get oil and crud in it.

Worf, where is the sender located? maybe a quick overview of the procedure?
thanx,
Kevin

See image below. The sender harness connector is the thing dangling. You can see the contacts for the sender in the center of the picture next to the oil filter.

As for the procedure? Raise front of car. Locate sender connector. Disconnect. Clean both halves. Re-connect. Install newly purchased plastic retaining clip if yours is MIA.
