Can't seem to find the problem to my rough idle, done everything I can think of , change plugs,leads,ignition pack, cleaned ICV, checked for vacuum leaks, and still no joy to solving the rough idle.. At it again today and the car now gets a fit of Reving up to 1100/1300 rpm when it's idling and sit there few a few secs and drop back down to about 700-80 again.. Anyone help me out here.? Patience is running thin at the moment all week trying to sort this idle and just seems to be gettin worse (318is)
