High idle in 380SL

[talulah]

Help please! I have a high idle in my 380SL. The idle control module was replaced by a MB dealer 6000 miles ago at a cost of $1700 (that included $760 for the module and several hours labor for 'diagnosis'). I don't want to face that again, or ever go back to that dealer. Also, when I accelerate out of a corner the engine has very little power, almost cuts out, but recovers when I ease up on the accelerator. Maybe related problems?

Maybe not connected to this at all, but my anti-lock brake light now stays on all the time (after a recent brake fluid change). Just mentioned this in case there's an overall electrical problem.

I love the car -- it has only 56000 original miles, but I need some good advice on how to fix the problems, especially the high idle. thanks
