It only gets up to temperature in town driving, on the run it never makes 90 but sits around the mid mark, put that down to winter temp's as I have never had a GTV (or any car with a specific centigrade indicator!) so I will change the stat, cheers alfapush for that. It could be a combination of things I suppose, I will do a process of elimination (cheapest first) I was looking at the FiatECUscan software (now with the older GTV'S ECU'S catered for) ,that seems very interesting, it could possibly pinpoint any other, related problems. Of course I would need to learn how to use it first! . Will put some injector cleaner through the system but I need to find out why she's burning rich it could be that the cat has been damaged with excess vapour, as the exhaust gas stinks of petrol! As for running ok, sometimes & not very often, upon starting she dies if I dont keep the revs up for a while. ie wont idle. will keep at it and keep all posted as to how I get on as it could be usefull for someone in the future.
