Question about 1993 Mercedes-Benz Mercedes Benz 400 Class

1 Answer

I have a 1993 400sel that runs on 4 cylinders only

I have a 1993 400sel that runs on 4 cylinders out of 8. Cylinders 1,4,6,7 all fire properly, cylinders 2,3,5,8 do not fire. I have injector pulse, & spark at all cyl. I have replaceds both dist. caps & rotors. Compression is good on all cylinders (120-140) The "odd" thing is that the left distributor supplies spark to cylinders 2,3,5,8.
