Thread: Struggling during power!

hello guys.


so we finally have the new 3.9 in and we have hit another problem.


at idle the motor is fine.


under acceleration in splutters and struggles.


then once at speed, cruising, its fine.


we have checked the timing and its almost dead on.
we changed the plugs/leads/coil pack.
the fuel pump is working and filter new.
the dizzy is in good condition



the next thing is a compression test, but is there anything else we are missing?


thanks guys.

Dizzy is in good condition...

But is the timing advance working ok? How is the ignition module?
