So my Gti has been stood up for a year but has been started reguarly and driven around with no problems. Yesterday I wanted to get an MOT on it as I want to insure it in May when I am 25. I thought best do it early to sort out any little problems it may have so I can then just use it when its insured Anyway started it up fine from cold but it was running rough. It seemed to be overfuelling. If you held the revs it runs fine. Once warmed up the overfuelling was worse it would tick over and then cut out. I have checked fuel and spark all good. I am thinking its either a coolant sensor of AFM. Not 100% sure about the AFM as it shouldn't get worse when its hot if the AFM was the problem should it? Also I have adjusted the AFM before and it was then spot on. It had a coolent sensor a couple of years ago as well. Before when that was causing trouble it ran fine when it was cold but overfueled when it was warm. Similar to now but it was much more obvious which makes me wonder if its not the coolent sensor? I havent had time to play with this yet hopefully at the weekend I will get a bit of time but I was wondering if anyone else has any ideas of what I should look at that could cause this problem.
