Hello!
I having some trouble with a s54b32.
Engine missfire betwen 5500rpm to 6000rpm. We have changed sparkplugs and ignition coils but no difference, it is possible to to reduce the missfires a bit if we go wery lean. I have also tried to play around with different ignition settings like dwell time etc.. but no difference
