Now fixed,the front 3 spark plugs are now changed,also had idle valve taken off along with throttle body and had them cleaned as deposits build up! 3 back plugs to follow as more tricky to get to! Fault showing was wiring to bank 2,4 and 6 I personally think the lifetime plugs needed changing! As it's back to a luxury flying machine again.
Hi I have 03 plate x type with misfire on 2,4 and 6 Coil pack at the moment,my mechanic said it's the wiring to the coil packs breaking down! Has anyone had this trouble?
