General HELP PLEASE!!!!!

[mikeknight]

Hi guys,
After some help if you don't mind??
I have a 61 reg Punto Evo dualogic. When pulling off the car shakes badly until you get going and seems to do the same at every gear change. I thought initially the clutch so we changed the clutch and its still there, we also changed the clutch fork at the same time. i also have replaced the following parts as a process of elimination, gearbox, diff, robot (complete unit), drive shafts, Throttle pedal, throttle body and gearbox mounts There were fault codes in the car that have now gone however the fault is still there the codes were...

P1770 No accelerator pedal information, present.
P1819 Engine torque (from CAN) present
P0856 VDC messages (from CAN) intermittent
P0710 Temperature (from CAN) present

Any help is very much appreciated
Thanks

Have you had the kit to bleed Selespeed, reset bite point, etc?

Hi yes done that...

Ok, seeing only engine errors I wondered if you had no communication..
But that's obviously not the issue

So in a steady run, in the1 gear.. Does it run really well, or still has hesitancy?
(have you replaced the earth cable)

Just thinking a non. gearbox issue..

Member @irc seems to have the most experience of this system

Hopefully can add to this

I agree i am also thinking a non gearbox issue. Yes in 1st gear when you get to walking speed it holds steady as it should it just when the car starts to move. It also does it although much less violently on change up to second and i cant notice it in 3rd and above. I have also changer the earth cable on the top of the dualogic unit.
