This is a CIS(constant injection system) related question, so it is
probably best asked on the main quattro list since 200q20v's are EFI;
the systems are very different.
However, neither system has an idle adjustment. CIS cars have cold
enrichment valves; both also have idle stabilization valves(which
bypass the throttle) to control speed(on both, the ISV can get gummed
up with oil; throttle body cleaner will do nicely). Sometimes
problems like these can be caused by a faulty temperature sender,
causing the ECU to not activate the cold enrichment valve.
