sick of it at this stage, thought it was fixed as i changed the alternator and battery yesterday as i thought that was it but on the way to cork today but the car was acting up again and ended up in leaving the car in a car park.. i also changed the king lead today, but there was no difference. when i left cork the revs were bouncing away again for 5 minutes or that way, cruising on the way home there was no problems until i came to back roads when i had to go to low gears or stop where the revs would bounce away again and engine management light came on. it was getting slightly dark when i was nearly home so i put on my lights and the revs would bounce immediatley, this surely has something big to do with it? any info much appreciated
