hi

my grande punto usually idles at around 700-800RPM. BUT today got 2 miles from my parents and the alternator drive belt snapped so i nursed it the 2 miles back with no electrics on to save battery life, i got my mum to go to europarts in her car to get me a new belt... its all fitted but now its idleing at 1100-1200RPM and i honestly dont know why any help or suggestions?? please

thanks
pete

First: have the ECU read at a dealer for stored faults.

ill put up with it for few months till i get all my diagnostics equipment dont use garages way too expensive for me lol
