OIL PRESSURE FALLS RAPIDLY AT IDLE!!!!
OK I am freakin out here!!!
When I start it up the oil pressure is fine.
Its at 40-47 psi. When it finnaly idles down it goes to 25-33 psi. But when I put it into drive and go down the road I look down at the first stop light and its AT
FU(KING 14 PSI!!!!
One time it hit 12 psi and I put it into neutral and it went up to 14 to 15. My car idles at 600r's. But thats normal idle. But here's the weird thing. My oil pressure warning light hasnt come on yet, I talked to ward and he said his comes on at 18 psi. I have checked the light and it does work. PLEASE HELP!

the movement on the oilpressure guage should not be quick. Get either a mechanical oil pressure guage(recommended) or a new oil pressuse sending unit... (like $7 at autozone)
I used to have this same problem, but mine started doing that right after I did a motorswap... I was freakin scared!!! new sending unit fixed it all...

Even 12 psi at idle (600) is plenty for a good motor. That's assumeing the indicator is right, if it is everything's OK.
Average rule of thumb is 10 PSI for every 1000rpm. So at 3000rpm you should see at least 30psi oil pressure, if not then worry.

I agree with John.
Low oil pressure light will usually come on around 5-7 psi.

bowtie,
Digital dash or not, the display will only use the information it is provided. The D/A/ converter still relies on an accurate signal from the ANALOG oil pressure sensor.
Verify the readings with a mechanical gauge and go from there. If the oil pressure is truly low, you might want to consider exploring the owners' manual for options about oil viscosity choices. SAE 30W synthetic might solve your problem if the sensor is accurate.
Later,
Vader
