    so i got the car back from the last issue with the cam sensor being replaced.
    took the car out today and after about 30 minutes, it felt like i kept losing the left bank again. if i was loafing it would stutter and hesitate, but if i then pushed it, the bank would light up and run. this happened at all speeds and gears.

    since the cam sensor was just replaced, could the mechanic have put it in wrong? or is this something else? i was thinking it cant be the distributor or the plugs coz it was always the left bank (at least it sounded like that).

    any thoughts before i take it into the mechanic on monday?

    Similar symptoms with my car. Mine are barely dectectable but I took the car to Ferrari of Denver anyway. In my case, the relays behind the fuse box are being replaced and moved a short distance. Active use of the car, and therefore the fusebox, seems to produce issues in that location with subsequent engine hesitation. After relocation of the relays, the computer for each bank will be tested to make sure they are still working correctly after 23 years and 11,500 miles. If not, we'll take that step next.

    I'm confident this will resolve the issue. Ferrari has rated the professional tech at FoD as one of the top in the world and I think he's on track.
