Kev,
They reckon tie it in with every 3rd oil change (assuming you follow extended 15-20k changes) so that's 45-60k. If yours were done at 47, then thats about right, 90k for the next set! |

Looks like you only have 11K on the plugs. hmm... I'd pull the #6 one out and compare it to the rest.
Coil packs are easy to check, swap the coilpack between two cylinders and see if the misfire changes with it. Injectors are possible, but rare, especially if you have been through the injector/HPFP recall. Good luck! Quote:

Just curious I had my coils replaced under recall their recently, does that mean they would automatically do the plugs along with that or not?
