Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Clean the Throttle Body

Tools Required: Throttle body cleaner, soft brush, clean rags
Remove the air intake duct connected to the throttle body.
Spray throttle body cleaner into the throttle body and use a soft brush to gently scrub any carbon buildup.
Wipe clean with a rag and ensure the throttle plate operates smoothly.
Reattach the air intake duct securely.

3. Check and Replace Fuel Filter (if applicable)

Tools Required: Socket set, fuel line removal tool, new fuel filter
Locate the fuel filter along the fuel line (refer to the owner's manual for the exact location).
Relieve fuel system pressure by loosening the fuel cap and using the service port.
Disconnect the fuel lines from the filter using a fuel line removal tool.
Install the new fuel filter, ensuring correct orientation based on flow direction.
Reconnect the fuel lines and tighten securely.

4. Inspect and Replace Spark Plugs

Tools Required: Socket set, torque wrench, new spark plugs
Remove the ignition coil cover and disconnect the ignition coils.
Unscrew and remove the old spark plugs using a socket wrench.
Check the gap on the new spark plugs and set to manufacturer specifications.
Install the new spark plugs, tightening to the specified torque.

5. Reconnect Battery and Test

Reconnect the battery terminals.
Start the engine and allow it to idle for a few minutes.
Test drive the vehicle to ensure the hesitation issue is resolved.
