190e 2.6 Wandering Idle and Lack of Power on Take Off when Warm - RESOLVED
 

This issue has been plaguing me for a year.

Replaced charcoal canister... Mine wasn't even hooked up. This helped with mpg and pressure in the gas tank.

Replaced airflow meter. Old one had a hole worn through the black material at idle. This helped with the wandering idle somewhat.

Replaced ICV with new Bosch part. This fixed the problem. It's a totally different car from a stop. Went from almost dying when putting into gear when warm ... To laying second gear scratches and almost third gear scratches.

WoW :D
