Hi I'm new to this and have a 2002 ram 1500 quad cab 4x4 the oil pressure gauge drops to nothing and the check gauge light comes on. this is only at low rpms. When I get going again it goes back up. Has anyone had this problem and how do I fix it?
Thanks

 

It's probably the oil pressure sender, possibly just a loose wire, but you need to get a mechanical gauge on it to be sure.
