Fluctuating gauges
 

What can it be!?! My oil pressure gauge jumps all over the place. Sometimes it's low, sometimes high. I replaced the sender and it helped for a month or so but it's up to it again. Could it be some sort of an electrical gremlin or a gauge problem. I'm leaving on a road trip next month and don't want to watch a dancing gauge!

Instrument Voltage Regulator. It's inside the dash attached to the back of the gauge cluster. Most likely that's your prob. If you need help removing it, email me. You should be able to pick one up at an auto parts store for about $15. Good luck.
