Ve/wm statesman misfire possibly afm related

[Sstagg2005]

Wm/Ve statesman 6.0 litre L76

Misfires on cylinders 1,4,7 have tried changing plugs leads injectors clean fuel rail ect.

Pulled the valve covers didnt note any issues

Done a compression test all around 150 psi give or take so I’m guessing not a pushrod or anything

Also when driven it goes into safety mode/limp mode, seems to go away if light on the throttle.

Done some research into the afm i believe it is causing the issues

Anyone had anything similar?

And anyone on here put a dod delete on an L76, bonus if it was installed due to Afm causing problems. Cheers
Will update as I go I’m sure I’ve forgotten something cheers

what codes are causing the safe mode ?

what codes are causing the safe mode ?

Was throwing p0300 random/multiple miss I’m not sure if that would cause it, I’m assuming it’s tied into the fact it’s running like a pig and misfiring on 3 cylinders
