Hi everyone, just need a little help with my golf: 1. She's running a little rich, how do I adjust this? 2. On normal tick over, should it idle at roughly 800revs or more/less? & if I need to adjust it, is it the small screw coming out the back of the injector(facing the back of the car)? & also is the a certain way to do it? 3. I'm not sure of the actual part, but behind my injector there are a few pipes that are held together by a clip that seems to fit to a flat, rectangular flange on the back of the injector, with 2 bolts. I'm missing these bolts does anyone know the size of these bolts & where I can get some from(gsf etc?) Colour pictures would be greatly appreciated with your answers thanks
