Tip & How-To about Mazda MAZDA6
Check the 5" wide rubber air intake hose at the convolutes for splits that allow unmetered air into the engine. When this happens, the MAF sensor does not know this air is flowing into the engine, so it leans out the mixture generating DTC codes for Lean, Bank 1 & Bank 2.
Use duct tape for a temporary fix and buy a new air intak hose. This hose runs from air cleaner box to engine throttle body.
