Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal.
Ensure the vehicle is on a flat surface and use wheel chocks for safety.

2. Address Fuel System Issues

Step 1: Remove the fuel pump relay from the fuse box.
Step 2: Relieve fuel pressure by starting the engine until it stalls.
Step 3: Reconnect the fuel pump relay.
Step 4: Replace the fuel filter if it shows signs of clogging.
Step 5: If fuel pressure is low, inspect the fuel pump for wear and replace it if necessary.

3. Clean or Replace Throttle Body

Step 1: Remove the air intake duct connected to the throttle body.
Step 2: Use throttle body cleaner and a clean cloth to remove carbon deposits from the throttle body.
Step 3: Inspect the throttle plate for proper operation and clean any residue.
Step 4: Reattach the air intake duct securely.

4. Inspect and Replace Spark Plugs

Step 1: Remove the ignition coil cover using a socket set.
Step 2: Disconnect the ignition coils and remove them using a socket.
Step 3: Remove the spark plugs with a spark plug socket.
Step 4: Inspect the spark plugs for wear; replace them with OEM specifications.
Step 5: Reinstall the ignition coils and cover.

5. Inspect and Replace Air Filter

Step 1: Locate the air filter housing and unclip it.
Step 2: Remove the old air filter and check for dirt or damage.
Step 3: Install a new, clean air filter.
Step 4: Re-secure the air filter housing.
