So I'm trying to solve all the running issues by changing plugs, spark plug wires, pcv etc and the alternator gives up. I had to drive it just on the battery and the rev counter stuck at 4000 and a high pitched noise like a warning buzzer started in the cabin.
I've switched out the alternator and fully charged the battery off the car. Now I've reinstalled everything but the rev counter is still stuck and the noise is still there.
Any ideas guys please??
Cheers
