Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety before starting work.

2. Inspect and Clean the Air Intake

Remove the air filter housing.
Inspect the air filter for dirt; replace if necessary.
Clean the throttle body using throttle body cleaner and a soft brush.
Reassemble the air intake system.

3. Fuel System Inspection

Use a fuel pressure gauge to check the fuel pump pressure; refer to the service manual for the specified pressure range.
If pressure is low, replace the fuel pump.
Clean the fuel injectors using a fuel injector cleaning kit or replace them if clogged.

4. Spark Plug and Ignition System Check

Remove spark plugs using a socket set; inspect for wear or carbon buildup.
Replace spark plugs if damaged; ensure to use the correct type and gap as specified in the owner's manual.
Inspect ignition coils; replace any faulty coils.

5. Transmission Fluid Check

Locate the transmission dipstick and check fluid level and condition (fluid should be a bright red color).
If fluid is low, top up with the recommended transmission fluid.
If fluid is dark or burnt, consider a transmission fluid change.
