My 4x4 does this all the time, there are 3 multiplugs at the back of the engine fixed to the bulkhead, it may be what Tab has said, or bad connection in one of them, i'm sure it's the middle one, but check all 3, these ALWAYS fuck up and alot of people solder the wires toghether and bin the connectors all together.
It can also cause a missfire as the ecu doesn't read the correct RPM.

As above - I had exactly your problem and after changing loads of things I found it to be one of the multiplugs. I removed the plugs and soldered the wires together and it fixed the problem for me. That was two years ago and not happened since.

As you said mate, can also cause a misfire too, didn't realise it was a big problem that my rev counter was fubar, and that the misfire i had was related to this, until i got my secs monitor, the display showed the ecu was seeing double rpm of the rev counter so it was misfiring like a b*stard. Ok now though.
