Oil light on

Hey guys,
drove my car around to the gas station just now and noticed my oil light coming on when I was at a stop light. It was almost like it wanted to come on, at times looked like it was dimming a bit. When I accelerate, it turns off and when I put it in park, it turns off. This is the first time this happens, oil level is good and I have no leaks. Any input? Where is this oil sensor? Thanks!

its under the fuel pump on the 8R. its a one wire sensor it just grounds the light on the dash.

Cool, thanks. Im about to adjust the idle speed a little bit, someone suggested that because it only happened at a stop light when the idle is lower, goes away when I start moving. Thanks again

Check your charge voltage.
