I have in a way the same kinda problem with my 190 E, but i wouldnt call it an irratic idle, its more of a shake in the engine on low rpm's, on high rpm it gets ok. I got it examined by a mercedez dealer and they told me that one of the injectors or what ever u wanna call it in the "fuel distributer" is running rich, which causes the shake.Also on low rpm's i sometimes can smell gas while seated inside the car. Now does that mean that i have to replace the distributer or it could b fixed by the tune up? any suggestions?
