Rev counter probs

[iain.atkinson at tesco.net]

I have a strange porblem with the rev counter in my 90 20vq, when it's cold i.e first few miles in the morning the rev counter doesn't read correctly. It over reads in fact and will then fall to the correct reading then go up again. After a while it performs normally, all the other gauges work fine, car drives fine so i don't think it's the rpm sender.
