Idle problem

Right only had the car a week and it is my first zed, 1991 Jap spec TT.

 

The idel on the thing is rough as hell will not idle smooth when cold or warm and smells very rich. Will fault code the ECU tomorrow morning but what do I need to adjust / look at first?

 

also the car is fast idling when warmed up when coasting (holding clucth in while moving) and also when you pull up to a set of lights / junction any ideas?

    could well be a det sensor (code 34) or an engine temp sensor. but the ECU check will point to anything sensor related, after that its a case of checking vacuum hoses, but start with the easy shit first like the ECU diag and you might get lucky
