Im new here but iv got 04 1/2 lly with the quadzilla set on 50 HP and the spedometer seems to have a mind of its own, if i touch the key over to start a few times it slowly reset its self. any ideas would be great:o:

Cluster may be going out. Does it should slower or faster than you are really going? Does it stick at a #MPH but you are stopped?

Its a GM known problem. Are you still under warranty?

thanks!!!:)

Mine started doing that last week. I disconnected the battery and it went away but came back a while later. I took the gluster out and took it apart and it was filled with dust. I blew it out with the air compressor and it hasnt done it since. Hope this helps.
