Surely not still having that 'Jerky feeling, TPS not the issue or the fuel pressure regulator? Perhaps the 147 does need the Italian tune-up. Certainly hope someone reading about your challenge can offer some advice as I know this has been very frustrating for you.

I assume it's a manual?

Are there any warning lights, has it been scanned with Alfa Romeo specific diagnostic software for errors?

Could possibly be a failing fuel pump.
