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. Address Fuel System Issues

Tools Required: Fuel pressure gauge, wrench set, safety goggles
Check fuel pressure using the gauge attached to the fuel rail.
If pressure is low, inspect the fuel pump and filter for clogs or failures.
Replace the fuel filter if necessary and install a new fuel pump if it is not functioning.

3. Clean or Replace Throttle Body

Tools Required: Throttle body cleaner, socket set, screwdriver set
Remove the air intake duct connected to the throttle body.
Use throttle body cleaner to thoroughly clean the throttle plate and bore.
Reinstall the duct securely.

4. Inspect and Replace Ignition Components

Tools Required: Socket set, torque wrench, multimeter
Remove the ignition coil and inspect the spark plugs for wear. Replace them if they appear fouled or worn.
Reinstall the ignition coil, ensuring it is tightened to manufacturer specifications.
