Default Oil Pressure Gauge

Has anyone else had trouble with their gauge going nuts on them? doin about 70ish it would read about 50 then jump to 120 then go to 60 then 80... you get the idea. It all happens fast too... so i don't think that then actual pressure is changing like that. anyone else ever see this?

i would recommend you get a mechanical gague on it to verify the pressure...they i would look at the sending unit as bad, if that checks out your cluster has gone wacky
