Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the battery to ensure safety during the process.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.

2. Address Fuel Delivery Issues

Sub-step 1: Remove the fuel pump fuse and start the engine until it stalls to relieve fuel pressure.
Sub-step 2: Disconnect the fuel lines from the fuel rail and use a fuel pressure gauge to test the pressure. Compare with manufacturer specifications.
Sub-step 3: If low pressure is detected, replace the fuel filter if applicable, or the fuel pump if necessary.

3. Inspect and Replace Spark Plugs

Sub-step 1: Remove the ignition coil cover (if applicable) to access the spark plugs.
Sub-step 2: Use a spark plug socket to remove the spark plugs, inspecting them for wear or fouling.
Sub-step 3: Replace spark plugs with OEM specifications and torque them to the manufacturer’s specified values.

4. Check Exhaust System

Sub-step 1: Inspect the exhaust system for any visible damage or leaks, starting from the exhaust manifold to the tailpipe.
Sub-step 2: Remove and inspect the catalytic converter for blockages or excessive carbon buildup.
Sub-step 3: Replace any damaged components, ensuring all connections are secure and leak-free.
