Just want to wade in here for a second and say something;
There really was no need to respond in the way you did to the Coventry remark; it was a joke, that's all. The people who've commented here have helped you hugely, and will continue to do so as this forum is a wealth of knowledge, more knowledge on Fiats than you'll find at most garages these days, and as was quite rightly said, if you insult those helping you, they probably won't help you again and you'll be left fitting second hand parts to your engine that will either fall off or break in 3 months time.
I can't offer any technical advice, but your reaction to some of the most knowledgeable members on this forum really pee'd me off.
Best of luck with the car, but don't use 'I'm a woman' as an excuse, you'll make all us women look stupid, listen to what these guys tell you and learn from it so that if you DO need to go to a garage, they won't screw you over cuz you can tell 'em otherwise. Build up your knowledge from here to the point where you can fix things yourself. That's what I'm doing. 'I'm a woman' doesn't count as an excuse for being ignorant to the technology and engineering that you use on a daily basis.
