190E 2.6 idle problem
I am having problem with a high idle on my 2.6. I just replaced my water pump, and instead of taking virtually the whole front off the car, I unbolted the intake manifold. After I replaced everything, I put all the sensors, and their plugs back. I have since rechecked everything several times, and also tried adjusting some things, but I still have an idle that sits at about 2100 rpms when warm.
Any help appreciated!

Check for loose vacuum lines and vacuum leaks.

that happened to my 190e2.6 as well, and it was diagnosed as a faulty throttle linkage microswitch. Changing the microswitch solved the problem.
this is a small switch (hence micro-) that is situated in the area of the throttle linkage. You have to remove the air filter housing to get to it. i hope this helps
