Will the "Plumbing Valve" work with a 300CE (24v engine)?
I turned down the fuel mixture screw last night (car was way rich) and now my car will not idle when cold, and idles very low/rough when warm.... As I posted before, the PO probably used the mixture screw to compensate for a bad ICV... Will the "plumbing" valve work with the 24v engine (M104)? Also, any other suggestions as to why the car might be idling so low? I put a new air cleaner in, new plugs, replaced the torn rubber breather hose, etc.... TIA!
