I have a 1985 MB 280SE (M110 engine) totally rebuild, and till now it ran perfect!
One day the idle was rough like it turned on only 5 cyl, and now I cant even start the
engine anymore. There are sparks, and gas
I changed the electronic module but without result.
Could it be the distributor? How can I test it?
Where to look first?
Thanks for any help,
