166 has become sluggish
Anyone had a problem with their 166 becoming sluggish and slow to pick up? In the last couple of months my 2.5 sportronic has suffered these problems; in the morning it won't pick up for the first half mile and even with the engine warm it is reluctant to go above 4000RPM before the engine starts resisting. On hills it is a particular problem and the car needs a good run up to overtake.
The local Alfa garage has done the diagnostic tests without finding anything and although on tickover it sounds perfect they want to check the timing - the cambelt was changed 20,000 miles ago after snapping a week before it was booked in for a service and cambelt change.
It is about four hours labour just to check the timing, they tell me, so I wondered if anyone's had this problem and can come up with any other possible causes before I spend hundreds on checking something that they might find is ok after all! The car's done 80,000 miles and had new valves after the cambelt damage and there's nothing wrong with the plugs.
Any suggestions gratefully received!
