I have run my 1994 Audi 100 (A6) 2.6 V6 (ABC engine) for 10 years with virtually no major problems, but a while ago it started having intermittent running problems. When warm it often won't idle at less than 1100rpm, sometimes as high as 1400rpm. From cold, sometimes it just cuts out and I have to restart, keep the revs up and drive until it gets some heat into it. I can cope with these instances, but there is an associated problem when I decelerate - there is a time lag which means the power is still on after I've lifted the throttle. This makes the car jerk as it comes off suddenly and this erratic behaviour is not pleasant in traffic.
I have had the car tested by a local garage and they say nothing shows up on a diagnostic check. They seem to think that it is a problem associated with the throttle body and after they cleaned this the car ran well for a whole week! The problem then returned. I am not convinced that a repeat clean will cure the problem and feel that they may have just accidentally effected a temporary cure by carrying out the work.
Any ideas / comments would be much appreciated.
