my Volkswagen Golf MK7 (2015-2019) feels like it is stalling while driving, is it normal?

Solution

1. Preparation

• Gather all necessary tools and parts.
• Ensure the vehicle is parked on a flat surface and safely secured with wheel chocks.
• Disconnect the battery to prevent electrical shock during repairs.

2. Check and Replace the Air Filter

• Locate the air filter housing and unclip it to access the air filter.
• Remove the old air filter and inspect for dirt or damage.
• Install a new air filter that meets OEM specifications.
• Reassemble the air filter housing, ensuring all clips are secured.

3. Inspect and Clean the Fuel System

• Relieve fuel system pressure by locating the fuel pump fuse and removing it, then start the engine until it stalls.
• Disconnect the fuel lines from the fuel filter using appropriate line removal tools.
• Replace the fuel filter if it appears clogged.
• Use a fuel system cleaner in the fuel tank to clean injectors, following the manufacturer's instructions.
• Reconnect the fuel lines and reinsert the fuel pump fuse.

4. Inspect and Replace Ignition Components

• Remove the engine cover if applicable.
• Disconnect the ignition coils from the spark plugs.
• Remove the spark plugs using a socket wrench, inspecting them for wear or deposits.
• Replace any faulty spark plugs with OEM equivalents and reattach the ignition coils.
• If ignition coils show signs of damage, replace them as necessary.

5. Test the Throttle Position Sensor

• Locate the TPS on the throttle body and disconnect the electrical connector.
• Use a multimeter to measure the voltage output while slowly opening the throttle.
• Compare the readings to the manufacturer’s specifications.
• If readings are outside the acceptable range, replace the TPS.
