Did you fit new plugs when you replaced coil pack?

[DGW]

What is the make and part number of the coil packs you are using?

[4x4mark]

Did you fit new plugs when you replaced coil pack?

no mate

[patrolman]

always fit new plugs when replacing a coil its usualy a high resistance in the plug that shorts the coil,you should replace the coils in pairs 1+3 2+4,but the coils all wear at the same rate , bite the bullit replace all four.

Check the plug gaps, wrong gapping can and does blow coil packs.

[chrisjackson]

yeah as above, i think gap should be 0.028".

worn plugs can cause coil failure. dont always need new plugs just re-gapping.

also check plug torques as plugs that are incorect torque let fuel through which can cause an issue

This has the bolt down coils doesnt it?? AGU engine code? if so the ignition amplifier on the airbox could be playing up, i found that unplugging mine and putting some electrical grease on the contacts has stopped an intermitent missfire i was having

The 2002 4X4 has the ARX engine with push on coil packs.
