I bought this 2016 murano about a month ago for a decent price. It drive well and had no issues. While in line at the emissions center it started started acting up being jumpy and wanting to stall and the check engine light came on. Checked the codes and had a misfire and lean codes. Put in new plugs and saw that the intake hose had some big tares so I replaced it with a new one, also replaced all the filters and cleaned the MAF sensor. Car drives great now and passed emissions but everything few days the check engine light will come on and say bank 1 &2 are lean (p0171&p0174). I’m suspecting there to be a lose of corroded wire for the MAF sensor since after doing some research that seems to be a common problem. Any advice or ideas on what it could be and what I should look into before throwing in the towel and giving it to a actual mechanic (I’m a weekend mechanic for my own cars)?
