riding along everything is fine.. Stop at a light gauge goes crazy.. pull away its back to normal.. bounces like a ball. Put it in N stop park stops its just when I stop an its in drive.. give it a bit of gas an it stops..

Could be the oil pressure sending unit/sensor. Very easy to change out. Easily accessible under the engine. Buy a new one for around $12, unscrew the old one, pop the wire off the back, plug that wire onto the new one, wrap a turn or two of teflon tape around the threads, screw it into the engine.

Just got one waiting on a friend to bring socket I don't have

1) Good news scenario: Could be just the sensor.
2) Bad new scenario: Bearings could have some wear and starting to lose a bit of pressure. Doesn't mean your engine is toast, just that it doesn't meet the pressure your sensor likes to see.

Hopefully it's just good news.

To me, it was easier using a pair of channel locks to screw it in there. I removed the old one with channel locks. Put two small loops of teflon tape on the threads, and used the channel locks to screw it into the engine. Took only a few seconds.

update..

as you can see put in a new sensor all was good.. Drive for awhile an now it goes crazy again but only when at idle.. bounces all over the place. Press gas all is good get to light bounce put in park normal .. what the hell am I missing here..

Maybe the gauge is going bad or like qdeezie said "maybe your bearings are wearing out".

I've had vehicles and friends vehicles in the past that had no oil pressure at idle but had a little when the rpm's increase. The motors ran for years that way.

put on a manual gauge psi stays steady at about 10 psi rev engine goes up to 25 are so.. seems to hold about 15 while highway driving.. should I change oil pump are is that psi okay
