Very !! erratic idling cold or hot
I have a T reg 146 1.8 T.spark. Very erratic idling. Needle can go 3/4 way round makes no difference hot or cold.. MAF replaced recently. LAMDA about 20K ago. Carbon removed from carb intake. No difference. Drive belt just shredded a pulley needs replacing (guide pulley? have taken it out and it is smooth not toothed). Cam, tensioner variator replaced about 2K ago. Have lived with this prob for about 3 years but it is now worse than ever cutting out for fun.
Also passenger window switch not woking but works from master switch in middle. Other slight probs (sump plug leaking) but this will do for starters if anyone can help.
