m104 Misfire
My '94 E320 just started to misfire.
I checked the HT from each of the 3 coils using a clip on timing gun and found that there is no output from the rear coil to plug 1. Swapped the coils around, fault stays with whichever coil is at the back. Same with the HT leads (1 & 5). So, I think the may be a fault with the feed to the rear (6) coil. How can I check this? The feed, presumably, come from the ECU. Is there any way to trace this fault back? Or, have I missed something simple?
