How do you adjust the idle mixture on a 92 500sl?
I had a rythmic slight rough idle that when I turned the AC on, it went away.
Replaced the O2 sensor with a mustang model, smogged the car and the resulsts were impressive, very clean burning car.
But the slight miss at adle was still there. Last weeekend decided to try to find the problem and stuck a small crewdriver into what I think is the idle adjustment spot, small hole behind the air intake at the fuel distributor area. I pushed down onto what appears to be spring loaded screw and turned it, the car died. Now the idle is smooth. Great result but unsure what I actually did and is not how I like results to come about.
So whereh is the idle adjustment mixture screw located and what is the correct adjustment?
