Hi guys, new to the forum as I've just got my first P6, a '71 V8. Got a few probs that I'm trying to sort out in time to take it down to Goodwood on our first roadtrip together, one of which is the revcounter. When I first drove the car the rev counter was fluctuating wildly whenever the box kicked down or throttle depressed. Now, when I start the engine, it jumps straight up to 4500 at idle (the engine's prob doing about 1000 rpm), this makes the needle plough into the red when driving. Anyone got any ideas?
