Help! Engine light coming on and misfire - Southampton

[conaero]

Have you checked to make sure you have the right cylinders? They are numbered unusually on the F136.

View attachment 85250

Also check the connections to the injectors, if you have a automotive stethoscope you should be able to hear them fire.

Not quite, it’s like this:

4 <> 5
3 <> 6
2 <> 7
1 <> 8

I had misfires due to bad spark plugs, fried the cats. Not the best experience.
