Rpm gauge has a mind of its own

[Black mamba]

Just as the title says.. I can be driving along at 65 and 2600 and all of a sudden my rpm gauge shoots up to 3500 or 4000 , now the engine does no rev at all.. And I learned I can fix this by tapping on the cluster .. What you guys think !?

Time for a new cluster lol

Il prob just replace the rpm unit and see what happens

Just make sure it's synchronized with your truck though man. I seen it to a couple guys where they thought it was spot on and it was like 20 mph off
