2001 ML320. CEL was on with P0175 and P0112 codes but otherwise the car would run OK. Installed new AMM and threw the old one away. After the car was warmed up - driving was a problem, it would lose power on acceleration and hesitate, spit and spudder up hills like it was going to stall. After two days of this, I dug the old AMM out of the trash and reinstalled it. Now the engine runs without losing power but I'm getting the P0175 code again.
Did I get a bad AMM? or is there some other problem I'm overlooking. I've checked for vacuum leaks, cleaned out the EGR tube, which was very dirty. I have not changed the fuel filter but it probably needs to be done. Could this be the problem?
