My 98 Brava SX 1.4 hesitates really badly in 1st and 2nd gear.It baulks as if there is no fuel getting thru.Any reason for this?.

I've got the same thing

If you look back I have left a few messages about injectors. I am also having this problem and it is most obvious when cold (but still happens to a lesser extent when warm. My fiat garage are going to replace a belt and tensioner and the fuel sender unit. They ordered the parts today so i won't know if it's worked until the end of the week but please keep me updated as to your situation.
