Oil pressure goes to zero at idle after truck warms up

[jclick]

After my Tahoe warms up, whenever I get to a stop light and the truck idles, it starts running rough and the oil pressure gauge goes to zero. What would be the cause of that? Thanks.

Haha, you're having all sorts of issues aren't you? Try having an oil change, then look into the oil pump and make sure that's ok.

All sorts of issue? you are right... It's almost impossible to sell one of these vehicles now because of gas prices. I've got my weekends filled up with Tahoe work. I wish I could find a bottle of Tahoe Fix and be done with it.

Haha I hear you. I want a bottle of that too
