Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety during repairs.
Allow the engine to cool down before working on any components.

2. Address Air Intake Issues

Tools Required: Flathead screwdriver, socket set, vacuum cleaner.
Remove the air intake duct and visually inspect the air filter.
- If the filter is dirty, replace it with a new one.
Check for any obstructions in the intake manifold.
Clean the throttle body using throttle body cleaner and a soft cloth.

3. Fuel System Inspection

Tools Required: Fuel pressure gauge, wrench set.
Disconnect the fuel pump relay and start the engine to relieve fuel pressure.
Connect the fuel pressure gauge to the fuel rail and check the pressure against manufacturer specifications.
- Replace the fuel filter if pressure is low or inconsistent.

4. Ignition System Check

Tools Required: Socket set, multimeter.
Remove spark plugs and inspect for wear or carbon buildup.
- Replace spark plugs if worn or fouled.
Test ignition coils with a multimeter to ensure proper resistance.

5. Transmission Fluid Check

Tools Required: Transmission fluid dipstick, funnel.
Check the transmission fluid level using the dipstick.
If low, add the appropriate type of transmission fluid as specified in the owner's manual.
Inspect for signs of burnt fluid and change if necessary.
