It starts 1st time when warm, and from cold on a summers day 11am or so, but find 1st thing from cold and when left for 8 hours, turns over fine but will not idle and have to hold the revs up for 30 secs, then absolutely fine when driving... sort of suspect water temp sensor but reads ok on dash ???

Have K&N filter, splitfire plugs and leads, fast road cam fitted and battery is fine... any help or ideas would be VERY much appriciated.

Does the engine have an automatic choke? Perhaps the choke/idle control valve are playing up? If you have a manual choke, perhaps the choke is not opening properly.

Na, all ecu controlled on mk 2 turbo have got temp sensor £8 from fiat so ill try and see how it goes.

Good idea - and water temp. gauge on dash has separate sensor anyway. Let us know if it's fixed?
