Hi, I have a 93' 190e 2.3. A few weeks ago, it felt as if it started getting rougher when trying to start it. After a few more days, it wouldn't start until a few tries with the throttle to the floor. I figure the injectors might be dirty? I'm replacing the fuel filter as a precaution. Another thing to note is I relocated a job that was in close proximity, so I was running the gas tank down pretty low. There could have been bad gas/crud at the bottom of the tank.. Any thoughts? I'm new to this vehicle and I've got a long list of repairs needed, but this is a necessity right now. I'm trying to make this last me through college. Any help, ideas, and thoughts would be appreciated!
