Right on saturday i was driving home from town and was coming up to a round about and my car engine cut out . First i thought i stalled so tried starting it put seemed to take a while then the engine cut out again. So i pulled over a stopped and it seemed to be struggling to idle and then cuts out but its fine at higher revs? . Got it home and left it for the night and started it on Sunday took ages for it to start and it sounds rough idling but after 1000rpm it sounds fine. I think it could be spark plugs or fuel injecters but just wondering what other people think. The car is a mk4 1.6 16v twinport.
