Hi. The decatted s3c has just started cutting out after rough idling at traffic lights etc. It is also missing badly at low revs less than 2000 rpm. Any ideas? It's the MAP system without the air flow meters.
Could be worth checking the fuse box in the nearside footwell, mine had a loose 25amp. caused it to splutter on rough roads and finally failed to start, a quick wiggle and all was well.
