I am new to this forum so sorry in advance for any missteps...I have a 2002 SLK 230 that was making a marbling noise from the super charger. I had a mechanic replace the super charger snout with a rebuilt one. the noise is gone but now getting P0101, P0243 and P0301,0302,0303,0304 codes. and runs rough and lacks any power when driven. I just called the mechanic and he said he would get with me soon. In the intrum I figured I reach to you guys to see if anyone had the same experience after having a super charger rebuilt. I'm thinking something is not plugged in correctly like a vacuum hose or a connector when re-assembled. Thoughts?

 

check to see if the air inlet hose into the filter housing is attached, look close. check for disconnected vacuum hoses. is the cel light on? may need codes reset.

 

Thanks will do...Much appreciated.
