So I've had my Mk2 Golf GTI 8v for a while now and I've fixed a lot of problems, but there are a few that I have been unable to fix. The idle is extremely unstable when first started and will vary from 750rpm to about 1250rpm and almost stall. After it has been running for a while it settles down until you start driving and stop again and then the same happens. The second problem is that the car is running rich, from what I've worked out running about 12L/100km or more. I have had the AFM and spark plug leads replaced, as well as the blue coolant temp sensor and although this has increased the cars performance greatly, these two problems are still present.
I don't know a whole lot about cars and I am unsure of weather these things are related but I really want to get it fixed as soon as possible because I can barely afford the fuel, so I was wondering If anyone has had the same problems and knows what it could be?
Thanks
