2000 Infiniti G20 OBD Code P0100 and Pending P0325: Hard Start, Stalling, No Acceleration
My 2000 Infiniti G20 is showing OBD fault code P0100 and a pending code P0325. The vehicle experiences hard starting, fails to accelerate, and stalls unexpectedly. This issue occurs under normal driving conditions. Code P0100 indicates a malfunction in the Mass Airflow (MAF) sensor, which can trigger 'limp mode' limiting engine RPM. The pending P0325 code suggests a misfire in cylinder 5, potentially due to worn spark plugs or ignition issues. I've already checked basic components like air intake ducts and MAF sensor connectors, but the problem persists.

This often results in hard starts and poor acceleration. For your 2000 Infiniti G20, begin by inspecting the MAF sensor connector and all air intake ducts for debris or loose connections. A dirty or faulty MAF sensor is a common cause of this issue.
