I think you should take her into Percival to get the code read/cleared. They won't do any work on it if it's something with the gauges but at least you'll know what the code is. It's probably like guilty said with like one wire on a harness isn't making a good connection. Or maybe due to the massive light output from the gauge your alternator just can't keep up. :D JJ

Just get the damn code read and quit being a whiny bitch.
