I have read up on these problems my main concerns are the 171,174 codes. I have been told to try to clean the mass air flow sensor is this a good choice of options and how do I go about removing it safely and cleaning it. As for the other two codes any information on them as well would be appreciated. Main concern is the not starting, and idling really low which are symptoms of the 171,174 codes I have been told. Any advice would be great.
