Possible Causes of Jerking Sensation During Acceleration

There are several potential reasons for a jerking sensation during acceleration in a 2016 Ford Escape. Identifying the root cause may require some diagnostic work. Here are some common issues that could cause this problem:

1. Faulty Spark Plugs or Ignition Coils

The spark plugs and ignition coils are essential for proper engine combustion. If either of these components is worn out or malfunctioning, you could experience a jerking or sputtering sensation during acceleration.

Solution:

• Inspect and replace faulty spark plugs.
• Inspect and replace ignition coils if necessary.

2. Dirty or Failing Fuel Injectors

Fuel injectors deliver fuel into the engine. If they are dirty or malfunctioning, the engine may not receive the appropriate amount of fuel, leading to a jerking sensation.

Solution:

• Use a fuel injector cleaning solution to clean the injectors.
• If cleaning does not resolve the issue, consider having the fuel injectors professionally inspected and possibly replaced.

3. Faulty Mass Air Flow (MAF) Sensor

The MAF sensor measures the amount of air entering the engine. If it is not functioning properly, the engine may not receive the correct mixture of air and fuel.

Solution:

• Remove and clean the MAF sensor with a suitable cleaner.
• If cleaning does not solve the issue, consider replacing the MAF sensor.

4. Transmission Issues

A transmission problem could also cause a jerking sensation during acceleration. This could be due to low transmission fluid, a clogged transmission filter, or other mechanical issues.

Solution:

• Check and refill the transmission fluid if it is low.
• Replace the transmission filter.
• Consider a professional transmission inspection if the problem persists.

5. Throttle Position Sensor (TPS) Problems

The TPS monitors the position of the throttle and sends this information to the engine control unit (ECU). A faulty TPS can cause erratic throttle behavior.

Solution:

• Inspect the TPS and replace if found to be faulty.

6. Vacuum Leaks

Vacuum leaks can disturb the air-fuel mixture in the engine, leading to a jerking sensation.

Solution:

• Inspect all vacuum hoses for leaks and replace any that are damaged.

7. Clogged Catalytic Converter

A clogged catalytic converter can hinder exhaust flow, affecting engine performance and causing jerking during acceleration.

Solution:

• Inspect the catalytic converter. If it is clogged, a professional cleaning or replacement may be necessary.

How to Diagnose the Issue

Identifying the exact cause of the jerking sensation may require some diagnostic work:

• Use an OBD-II scanner to check for any error codes that may indicate the source of the problem.
• Perform a visual inspection of the engine components such as spark plugs, coils, and hoses.
• If unsure, take the vehicle to a professional mechanic for a thorough diagnosis.

Final Note

Addressing a jerking sensation during acceleration in a 2016 Ford Escape requires pinpointing the root cause through careful inspection and possibly diagnostic tools. Once identified, the appropriate fix, whether it's replacing spark plugs, cleaning fuel injectors, or addressing a transmission issue, can be implemented to restore smooth operation.
