Gang, I was wondering if I could get help for some of my issues.
I have two cars that both suffer from high idle.

My 450SLC 5.0 and 500SLC. Both are suffering from high idle issues when warm.

In Drive, the idle is right around 1000rpm and in Neutral, it's right around 1600rpm. Any thoughts as to how I can adjust this?
