I have a 88 s4 vert and my oil pressure gauge is starting to act up. Now it will start reading near 0 as the car warms up and a bit after it warms up, and when i accelarate, where it would normally read 55-60 psi it will read id say about 30-40 psi. however after a few minutes, i havent had a chance to check really i;d say probably 5-10 minutes after driving it will act as normal and idle at 30 psi and go up to 55-60 psi when driving. Is my gauge shot? or is my car broke

Gauge is probably fine- check sending unit (most likely culprit) and wiring.

Mine does the exact same thing and it's due to a faulty sending unit. I haven't bothered changing it because I know there is good oil Psi. Besides, I'm switching to aftermarket gauges/sensors.
