I just bought a 2000 alfa 156, everything worked fine until tuesday when the fan belt snapped. Gutted but hey it happens! went to get a new one fitted and the car worked completely fine until they fitted the new belt. The second i left the injector failure light came on and i got a loud rasping noise with a slight vibration twinned with a slight loss of power starting just before 3000 rpm and finishing just after 4, this has been happening intermittently for 3 days now and is upsetting me greatly from enjoying my alfa. As I said its intermittent and once i hit 4000 all the wonder and glory that the alfa should be comes rushing back!
Any thoughts please, over tensioned belt left something loose? something worse?
And help would be greatly appreciated.
