A 2006 Nissan Frontier may be running too lean due to several factors, including a malfunctioning mass air flow (MAF) sensor, clogged fuel injectors, or a vacuum leak that allows too much air to enter the engine. Additionally, issues with the fuel pump or a dirty fuel filter could restrict fuel flow, leading to a lean condition. Checking for diagnostic trouble codes (DTCs) can help pinpoint the exact cause. Regular maintenance can prevent these issues from occurring.
Check for any disconnected hoses under hood and make sure fuel pressure is at proper spec.
