Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the battery to ensure safety while working on the vehicle.

2. Inspect and Clean Air Intake

Remove the air intake hose from the throttle body.
Inspect for obstructions or damage and clean the throttle body using throttle body cleaner.
Reattach the air intake hose securely.

3. Fuel System Check

Check the fuel pump operation by listening for its activation when the ignition is turned on.
Replace the fuel filter if it appears clogged or has not been changed recently.
If the fuel pump is faulty, remove and replace it according to manufacturer specifications.

4. Inspect Ignition System

Remove spark plugs for inspection; replace if worn or fouled.
Test ignition coils using a multimeter; replace any faulty coils.
Reinstall spark plugs and ensure they are torqued to manufacturer specifications.

5. Transmission Fluid Inspection

Locate the transmission dipstick and check the fluid level.
If the fluid is low, add the correct type of transmission fluid.
If the fluid appears dark or has a burnt smell, consider a transmission fluid change.
