Hi all, I have a problem with my 2001 (51, petrol auto) Lupo where it starts to judder/vibrate/shake/stutter after about 20 seconds of idling on a cold engine. It keeps stuttering for about 1 minute before it stalls. I can stop it stalling by holding the RPM's at 1500-2000 until the engine warms up (3-4 minutes). It's annoying and happens every single morning even when it's not that cold outside. I've heard it might be: Coil Packs Air Intake Throttle Valve Spark Plugs Throttle Body I'm not technical *at all* and have been to local garages who have charged me £30 for an inspection and said "we'll need to keep it overnight and test fit new replacements of all those parts before we can make a judgement" - which they want £100+ for. Any help/ideas will be greatly appreciated. Kasim
