01 clk320 idle too high
hey guys im new to the forum. I have 01 clk320 and i have a problem with my idle speed its started a month ago first it was idling at 1500 rpm. Ok than i changed throttle body and couple of hoses to make sure i don't have a vacuum leak and now its idling on 2500rpm please help me to figure it out. And i dont have any codes or mistakes recorded on my ecu

did you disconnect the battery and let the ECU reset adaptations after you changed or cleaned the TB? When I cleaned mine, it had a bunch of gunk on the back of the butterfly, and the computer was compensating the idle position for this, so when it was clean, then a lot more air was getting in and causing revs like this.
I would also try disconnecting the MAF as said above. This will cause the computer to go to sort of a default position with no input from the potentially faulty MAF.
