Oil Pressure Gauge
Mine is kinda crazy most of the time. Sometimes, it'll have no reading, but if I flick the gauge (or the cover panel over it), it'll go up to where it should be. Also, sometimes it bounces from high to low really fast and crazily randomly. The car runs fine, is this just a gauge issue?

Re: Oil Pressure Gauge
You have one of two problems or maybe both, I think its called the, Oil pressure sending unit in the engine is going bad or the oil pressure gauge itself is bad. Hope this helps.
