Carb Legal 1985 500SEL Running Problems
As the title says, I have a 500SEL with some running problems. At 151,xxx mi, it's been sitting for 4 or 5 years due to a developed running issue. Garaged in the dry desert climate of Southern California. Symptoms like rough idle and stalling at random times while driving point to a vaccum leak, however investigation may prove otherwise.
I have a shortlist of things to go over on labor day weekend, but I wanted to post up here in hopes that a second opinion may guide me directly to the problem. Has anyone else had these issues on the 5.0L engine and have a solution?
Bonus photos for reading this and helping me out. Your input is appreciated! I can't wait to have this thing running like a champ again.





1) Drain the gas tank and put new gas in it.
2) Check the Fuel Pump and change the Fuel Filter
3) Get the injectors checked and cleaned - Replace as need.
4) Check the Fuel distributor and Warm up regulator
5) Then Spark plugs etc.
Good luck
