my Ford F-150 has poor acceleration from a stop, what's going on?

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the battery to ensure safety during repairs.
• Allow the engine to cool before proceeding.

2. Inspect and Clean Air Intake

• Remove the air filter and inspect for dirt or blockages.
• Clean the air filter or replace it if necessary.
• Inspect the intake duct for cracks or loose connections and replace if damaged.

3. Test and Replace Throttle Position Sensor (if necessary)

• Disconnect the electrical connector from the TPS.
• Use a multimeter to measure resistance across the sensor terminals.
• If readings are outside manufacturer specifications, replace the TPS.

4. Check and Replace Spark Plugs

• Remove spark plug wires and use a socket set to remove the spark plugs.
• Inspect each spark plug for wear, carbon buildup, or damage.
• Replace with new spark plugs according to manufacturer specifications (typically torque to 12-15 ft-lbs).

5. Verify Fuel Pressure

• Connect a fuel pressure gauge to the fuel rail.
• Start the engine and check the pressure against manufacturer specifications.
• If pressure is low, replace the fuel pump or filter as needed.

6. Transmission Fluid Check

• Locate the transmission dipstick and check the fluid level.
• If low, add the appropriate transmission fluid as specified in the owner's manual.
• If fluid is dark or burnt, consider a transmission fluid flush.
