A decrease in fuel efficiency caused by emissions problems may be linked to issues in the engine o r emission system:

Faulty Oxygen Sensor: An oxygen sensor that is malfunctioning can cause the engine to run inefficiently, burning more fuel. It may also cause the car to release more emissions than normal.
Clogged Fuel Injectors: Dirty o r clogged fuel injectors can lead to improper fuel distribution, which can reduce fuel efficiency.
Exhaust Gas Recirculation EGR Valve Issues: If the EGR valve is stuck open o r closed, it can affect the combustion process, leading to reduced fuel efficiency and higher emissions.
Worn Spark Plugs: If the spark plugs are not firing correctly, they can cause incomplete combustion, reducing fuel efficiency and increasing emissions.
Solution: Have the oxygen sensor, fuel injectors, and EGR valve inspected and replaced if needed. Ensure the spark plugs are clean o r replaced. Regular maintenance and addressing these issues promptly will restore fuel efficiency and reduce emissions.
