Solution

1. Preparation

Gather tools and parts.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Spark Plugs

Remove the ignition coil packs using a socket set (typically 10mm).
Extract the spark plugs using a spark plug socket; check for wear or carbon buildup.
Replace with new spark plugs that meet manufacturer's specifications.
Reinstall the ignition coil packs and reconnect the battery.

3. Examine the Exhaust System

Elevate the vehicle safely using jack stands.
Visually inspect the exhaust for any holes, cracks, or loose hangers.
Tighten any loose connections or replace damaged sections of the exhaust pipe as necessary.

4. Check and Repair Vacuum Leaks

Inspect all vacuum hoses for cracks or disconnections.
Replace any damaged hoses.
Use a smoke machine to detect any hidden leaks if necessary.

5. Test and Replace Fuel System Components

Use a fuel pressure gauge to measure fuel pressure at the rail.
If pressure is low, check and replace the fuel filter if clogged.
If necessary, replace the fuel pump.
