Check Gauges Light & Bouncing Needles at High RPMS (Video)
 

Hey all,

My buddy Steve and I rebuilt the top end of my motor a couple weeks ago. No real issues at all, and this really isn't an "issue" either. When I get to higher RPM's through the gears I'm seeing the needles bounce and the Check Gauges light on. It's slightly annoying as don't want to get past redline. With bouncing needles it's hard to tell exactly what RPM I'm really at.

Here is the video:

I'll grab a better quality video shortly... Any idea's as to cause? I'm thinking BCM, gauge cluster itself, bad ground?

Thanks...

I'd start checking grounds. Especially since the engine was torn down.
