Hello hoping that I can get some help with a miss problem on my mb 72 280 se 4.5, car has a random miss that can take up to days to repeat, have replaced trigger point for fi, installed new plugs wires(good sti set not Bosch)crane electronic ignition, pull ecu to check for possible bad solder joint in board seems ok have heard that distributor can leak oil onto trigger points but they seem clean and are only 1 month old, any help or thoughts would be great,
