Just pulled the leads to each of the three coils on the right bank of cylinders and no change in engine what so ever.
Anyone suggest what might be causing all three down at same time,removing any one of the other three coil wires on left bank causes the engine to run very very rough.so left bank working . Swapped front right and left coil pack but still the same so coil pack is good
Suppose too be working tomorrow so will hope someone sends me some magic words...Thanks
