Check Engine: Lean Air/Fuel Ratio

I don’t know about Nissan, but our ford had nearly the same episode. I tried cleaning the maf sensor, and then given the myriad of other possibilities I took it to the dealer. They claim that they can read more codes than the auto parts stores, replaced plenum seal and some o rings and all has been good. It may be worth your while to have a dealer look at it as of all the possible fixes plenum seal and o rings never came up.
