TACHOMETER JUMPING AROUND
Problem - Car is running perfectly but the tachometer moves around at constant speed and at idle.
Possibility 1 - My car and other cars have had this problem and it always seems to be the earth/ground. Check that for starters.
Possibility 2 - Definitely check grounds and also check the wiring isn't corroded and check fuses and relays.
