The mass airflow sensor in your VW Jetta GLI is what determines how much fuel is necessary to run your engine efficiently by measuring the amount of air entering the engine. As a part of the engine management system, the mass airflow sensor helps adjust to certain changes, like altitude. If your VW Jetta GLI is having trouble starting, idling rough or has a sudden fast change in the position of the throttle pedal, this could be a crucial sign of a defective mass airflow sensor.

If your spark plugs or spark plug wires are bad or old, you will undergo a conspicuous poor performance and decreased power. In some extreme cases, your engine will have trouble starting or continuing to run. Worn spark plugs and plug wires can cause obstructed catalytic converter or damage to ignition coils and O2 sensors, leading to more pricey repairs.
• Your catalytic converter is bad or going bad. The catalytic converter is a part of your 2023 VW Jetta GLI's exhaust system. The catalytic converter's function is to turn the carbon monoxide created by the combustion process into carbon dioxide.
