I recently changed my dash cluster lights. They are still regular incandescent bulbs, not LED's, but maybe it's relevant. Anyway, I also removed the needles when I was in there (not sure why now, and wish I hadn't). I managed to get the fuel, water temp, and tach needles right on, but my speedometer is twitchy. From a dead stop, when I accelerate slow, fast, or medium, the needle hesitates to move until it suddenly jumps up to 20. It does this in every driving situation, speeding up or slowing down. I have tried removing the needle and resetting it, but it didn't help. When I shut the car off, the needle eventually goes back down to 0, and the needle settles to be around the right speed when it finally catches up, it just doesn't react instantly. Any ideas on what's wrong, or more importantly, how to fix it?
