got a mk3 astra 1.8 16v Nreg. engine management light has been coming on and staying on and today it started cutting out and then not starting again. before it cuts out, the rev counter needle goes nuts and does its own thing and then it just cuts out.
do i need to plug it in to a computer to see what the fault is or does anyone have any ideas of what i can try to fix it?
(it has been just been off the road for four months due to cam belt breakage and the battery has been changed if that makes any difference!)
