I let the car glow for 25sec yesterday morning, it fired right up and it did not miss/ stumble/smoke almost at all.
I just changed the pre filter+ main fuel filter, and did a diesel purge too.
I found a lot of gunky **** in the main filter and it had 04/05/2004 date written on it. I can't really belive the car ran with that one plus it was way overdue.
The old Benz seems to like that diesel purge stuff, I guess I'll have to do a cold start on Sunday and see the results bc the temp is supposed to go from 80 to 30
