Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety during repairs.

2. Inspect and Clean Throttle Body

Tools Required: Throttle body cleaner, soft cloth, screwdriver set, torque wrench.
Remove the air intake ducting to access the throttle body.
Spray throttle body cleaner onto the throttle plate and surrounding areas.
Use a soft cloth to wipe away carbon buildup.
Reinstall the air intake ducting and reconnect the battery.

3. Fuel System Check

Tools Required: Fuel pressure gauge, wrench set.
Locate the fuel pressure test port on the fuel rail.
Connect the fuel pressure gauge and turn the ignition to the "ON" position (do not start the engine).
Record the fuel pressure reading; it should be within the manufacturer's specified range.
If pressure is low, inspect the fuel pump, filter, and fuel lines for blockages or leaks.

4. Inspect and Replace Spark Plugs (if needed)

Tools Required: Socket set, torque wrench, dielectric grease.
Remove the ignition coil(s) on the affected cylinder(s) to access spark plugs.
Inspect the spark plugs for wear or fouling.
Replace if necessary, ensuring to torque to manufacturer specifications.
Apply a small amount of dielectric grease to the inside of the ignition coil boot before reinstallation.
