I posted last year with this problem, but have had no success. Basically, there is just no power in my Punto. I have a mk1 1.2i 75sx, and I had a go of my mates mk1 60 and his is way quicker accelerating than mine!. The car revs great until about 3000rpm but then it just dies, there is no pull at all. I have changed the engine, all plugs and leads and have had a new cat-back exhaust fitted by Longlife just before christmas. I have taken the car to Fiat and an italian car specialist near me, but neither has figured out what was wrong with it! Can anyone help, and suggestions would be greatl. Thanks.
