Hey have a question. My Nissan Rogue keeps tripping as mass air flow sensor code. I reset and cleaned it with mass air flow sensor with cleaner but it didn’t do much. Code came back, so installed a new maf sensor and the code didn’t come back for awhile. Then recently code came back. The short term fuel trim has been running around -6 during idle and as much as -15 when I’m hitting the throttle. Pretty sure it needs a valve cover gasket replaced, since it leaks about a quart of oil every oil change. About 3 weeks ago I put a quart of oil in cause it was low and the car ran fine for a few weeks with no codes. But now codes are back. When you start the car it sometimes acts like it wants to stall, or sometimes you’ll start it and it’ll shack for a few seconds.
