Oil Pressure Gauge

[nastety92]

I've been having an issue lately in the Yukon where the gauges bounces around while driving. The oil pressure gauge either stays on zero or is maxed on 80psi+. Is this just a gauge problem? The truck runs perfectly and I don't think we have a oil pressure issue.

Thanks,
Nick

Oil pressure sending unit. Very common issue. It's on the rear of the intake manifold by the firewall.

Yep, correct just did one for my father n law on his avalanche - not too bad - easy fix though
