Hey Mates! In this video I will show you how I diagnosed a P2191. This is related to a lean combustion mixture and the root causes might be multiple. This is raw content, with almost no editing. It's just me speaking out loud :)

The oxigen sensor is detecting a lean mixture, therefore requesting the ECU more fuel. LTFT are increasing every minute until a DTC is stored.

Root causes are broad, from a dirty MAF/MAP sensor, fuel delivery issues, vacuum leaks, PCV valve issues, HPFP problems, among others.
