My cars developed a bit of a problem, basically my rev counter only works sometimes.
It only works now and then when driving normally, but once you've been driving it hard it works fine.
Anyone know whats wrong?

 

No idea Gary, but its a bloody good excuse to give it licks all the time!

Problems sorted I replaced a couple of fuse's and cleaned the dizzy, and works fine now
