Hye guys, i just changed my plugs to NGK's, gapped at 0.8.
when i had a major service done, they put in either 1.0 or 1.1.
now, i have noticed that it has a miss at idle, but not high up in the rev range, ie not 4500 and beyond.
now, i will be upgrading to a set of splitfires, but is there anything else that can cause this?
it never missed at all when i had the wrong plugs in, but it was backfiring a fair bit when the other plugs where in. the backfiring has faded away a bit, but now i have this miss when im sitting at traffic lights.
thanks for your help in advance
cheers
