First thought: Is the vehicle stock? If not, please clarify any aftermarket modifications—such as performance chips, exhaust systems, fuel filters, or spark plugs. These can interfere with sensor readings. Additionally, having an OBD2 scanner to view live data (like fuel trim and oxygen sensor values) would help pinpoint whether the issue is due to a malfunctioning sensor or a system imbalance.
