got my car tuned, dont think that has anything to do with it, but i through it in just in case, my idle is jumping from 400-900 and my oil pressure is going all the way to 0 on the gauge, ive replaced the sending unit, my pump seems to be working fine, and out of the plugs i pulled they seem fine.....any ideas?

 

My car would idle erradically, and I had to keep on the gas to keep it running. Oil pressure guage went to just above the red line at idle but would climb above idle. I had a broken valve spring.

ZMAN

 

still looking for ideas

 

check the gauge

 

First thing I would do is hook up a mechanical oil pressure gauge.

 

Check the oil. I may sound like an *** with this but I hate it when I find something wrong than try to fix it and do all this crap and it turns out to be the most simple soulution just throwingn ideas out....

 

Sounds like a spun bearing.
