BA Falcon 4.0 6cyl Coils 2, 4 and 6 malfunction. Is it caused by limp mode or is it causing limp mode

[Aaren Myatt]

I bought the old ute from an abusive ex owner, it seems to be in limp mode but there's no dash indicator. It starts up normal firing all cylinders smoothly then when it stabilizes it falls into a rough idle and limited power as if its running on 3 cylinders like the codes indicate.

Although the fault being even numbered coils indicating to a pattern that could be beyond the coils themselves I changed them anyway and it made no difference. The transmission had a lot of metallic material in the oil when I drained it, though it selects gears and shifts smoothly. The vibration I originally attributed to the converter being buggered but since then I think it could just be because the 2,4,6 cylinders aren't firing.

 

What components is it worth looking at that could be causing this issue?

Could a damaged transmission or buggered torque converter be the case of this?

 

Any help or insight on this would be helpful, thank you.

 

 

I have codes

• 0352 Ignition coil B primary circuit malfunction
• 0354 Ignition coil D primary/secondary circuit
• 0356 Ignition coil F primary/secondary circuit
