Demon Controlled Rev Counter! Help!

[Russcoe]

I've got one for you guys, sitting at the lights today (idling), my rev counter starts winding around the clock to 9000rpm back to 4000 up to 10000 back to 3000 then stttles back at 700 all in the space of a few seconds....what the f*ck!???

Driving home from work it did it again....happens whilst driving too.

Anyone heard of this happening??? Easy fix? Or do I have to perform an exorcism?!

Any help much appreciated.

exorcism is due I think. Mine dropped to 0 rpm at the lights the other night but I think mine is just a lose wire behind the cluster, as I pulled it out the other weekend to change bulbs.

Did you notice anything else change? (lights dim/brighten, other gauges)

Have you done anything behind the dash lately?

I have the number for Ghostbusters if you want it!!

Is it only the rev needle moving or is the engine actually revving eraticly as well?

If my engine was erratically revving to 10k I would be more worries about finding the ignition to kill it than looking at the tacho...

i'm pretty sure its just the needle... i'd assume he would have mentioned the engine reving to 1000000000000 rpm
