Hi. I have a problem with my 1993 Audi. When it's cold and when driving around town, when I take my foot off the throttle car is still going for about 3 seconds, but on motorway everything is fine. I checked for leaks around inlet manifold and vacuum system seems to be in order too. I just have no idea what it can be. Maybe someone can help me with that? Thanks in advance.

HI, could be a sticky throttle cable,might pay to squirt some WD 40 (other makes are available) around the throttle body etc. :dunno:

Thanks, will check. Another problem I forgot to mention was at some point when engine is cold rpm will jump between 1100rpm and 1200 rpm and then stop.

Have you had a flat or disconnected battery recently?

Well, could be. Car was just sitting for about 1.5 years without driving. So will definitely try reseting ECU! Thanks for this mate. I was about to order new idle vale, as I though that could be faulty... but will try this first, before spending money...

EDIT: Can't find ECU/Ignition fuse, so don't hae anything to 'pull out'

The ECU fuses are the big ones, I believe labelled 'moteur' just disconnecting the battery achieves the same thing.

I managed to reset ECU (removed negative pole for 20min) and it seems to be more 'sattled down'. RPM still jumps when changing gears, but considerably less. So I bought new idle valve, as mine has done loads, hope that will sort it out. :aargh4:

New idle valve didn't work, did check throttle position; fixed that, didn't work either. Will try to reset ECU and Throttle will see whether that works. :zx11:
