My amp gauge did weird stuff and was all over the place and jerked when it moved. Conclusion was the stepper motor. I was out of warranty on mine too so I replaced them all with an "upgraded" version. Works great. At DP, roswell did a tutorial with pics that you can download. If you can't find it, let me know. Good luck.
Stepper motor going out?
I noticed that recently my speedo has been kindof not moving smoothly but more in a jerking manner. My other gauges all still move smooth. Is this a sign of the stepper motor going bad? I know GM had a recall on my year for this but I am way over the warranty. Any help? Should I just replace them all?

There is an LED mod for the bulbs too. Might as well check it out and fix it all while you are in there.
At DP there was a thread in the DIY section called "LED Dash cluster..." started by JHforman. He indicates that the bulbs still dim (post # 15). This was an excellent thread on the subject.
