Hey fellas has anyone experienced a jumpy tachometer needle?
Its in my rodeo wich is an isuzu really, it goes up when i turn to the left and down when i turn right, so its affected by gravity somehow and most of the time sits about 2.5 regardless of actual rpm, its annoying me!

Unless there's a known solution for the vehicle, my general advice would be to pull the cluster and re-solder all the connections on the daughterboard. Check for wires around the steering column that are pulling, pinching or rubbing.
