why does my Ford Explorer Fifth Generation (2011-2019) struggle to accelerate from a stop

Solution

1. Preparation

• Gather tools and parts required for the repair.
• Ensure the vehicle is parked on a level surface and the engine is turned off.
• Wear safety glasses and gloves for protection.

2. Address Throttle Position Sensor (TPS) Issues

• Disconnect the battery: Prevent electrical shorts by disconnecting the negative terminal.
• Locate TPS: Find the throttle body and identify the TPS.
• Remove TPS: Unscrew the TPS mounting screws and carefully detach the sensor from the throttle body.
• Test and replace if necessary: Use a multimeter to check TPS resistance. If readings are outside specifications, replace with a new sensor using the manufacturer's part number.
• Reinstall TPS: Attach the new TPS and tighten screws to the manufacturer's torque specifications.

3. Inspect and Replace Spark Plugs

• Remove ignition coils: Unscrew and carefully pull out the ignition coils from the spark plug wells.
• Extract spark plugs: Use a spark plug socket to remove the old spark plugs.
• Install new spark plugs: Gap the new spark plugs according to manufacturer specifications and install them, tightening to the specified torque.
• Reinstall ignition coils: Place coils back in their respective positions and secure them.

4. Check and Replace Transmission Fluid (if needed)

• Locate the transmission dipstick: Check fluid level with the engine running (if applicable).
• Drain old fluid: Remove the transmission pan and drain fluid into a clean container.
• Replace filter: Remove the old transmission filter and replace it with a new one.
• Reinstall pan: Clean the pan and replace it, ensuring a proper seal.
• Add new fluid: Refill with manufacturer-recommended transmission fluid.
