4000q erratic cold Idle
One last question. My 4000q Idles bad when it is cold. I know I have a slight vaccume leak but even with that fixed it still does it. When I first start it it varies between 1800 RPM and about 400 RPM. What gives. Also, that big, short vacuum hose next to the intake manifold keeps colapsing. IS that normal. I borrowed one off of another Audi and it did it too. Are all these problems inter-related. I think they are. On Hot days it even dies when I stop at a stop sign sometimes. When the RPM's drop they just keep dropping. What is wrong. Thanks.
