MY FIAT BRAVA 1.2 HAS STARTED REVVING ITSELF, IVE CHANGED THE MAP SENSOR AND THE STEPPER VALVE WITH NO LUCK, DIAGNOSTICS COME UP WITH THE MAP SENSOR OBVIOUSLY IT WASNT THAT. ANY SUGESTIONS WOULD BE GREAT.:bang:
Is this only at idle, or when you're driving?
if it is at idle, i would confidently say it is the ICV [idle control valve]. You can either clean it or replace it but make sure you don't adjust it.
Yep. Check also that -- I think it's the SPI model -- all the hoses are on, on in the right place, not blocked or cracked and that the throttle is neither overtight or interfered with by the stupid rubber nipple on the end.
