Here's one for the books... I was driving down the road and I noticed that each time I hit a small bump, the tachometer would drop to 0 and the oil pressure guage would drop to 0. Then, it would come back the next time I hit a bump. At one point, both gauges spun around 360 degrees! I knew if the speedometer did that, I would surely break the time/space barrier. From the looks of it, it's a loose sensor somewhere. Anyone have an idea?
