Swapped coils - no misfires

catcher22 · 05-30-2012, 12:53 PM

Changed all 6 plugs and afterwards found misfires on 5 and 6. Swapped 5 and 6 to 3 and 4 and misfires went away. Scanned with BT a few times and continue to show no codes....reset all adaptations as well.

The problem? Getting really crappy gas mileage (like 15-16mpg).

I understand it could be anything from incorrect torque (I did measure), to vanos, injectors....but I am not sure at this point.
