Solution

1. Preparation

• Gather tools and parts required for the repair.
• Ensure the vehicle is parked on a level surface and the engine is off.
• Disconnect the battery to prevent electric shock or short circuits.

2. Addressing Error Codes

• Sub-step 1: Use the OBD-II scanner to read any trouble codes.
• Sub-step 2: Research codes to determine specific failures (e.g., P0300 for random misfire).
• Sub-step 3: Clear the codes after taking necessary actions; re-scan after repairs.

3. Fuel System Inspection

• Sub-step 1: Inspect the fuel filter for clogs and replace if necessary.
• Sub-step 2: Check fuel injectors for proper spray pattern; clean or replace if faulty.
• Sub-step 3: Test fuel pressure with a fuel pressure gauge; replace the fuel pump if pressure is low.

4. Idle Air Control Valve (IAC) Service

• Sub-step 1: Locate the IAC on the throttle body.
• Sub-step 2: Remove the IAC and clean it with throttle body cleaner.
• Sub-step 3: Reinstall the IAC and ensure it is securely fastened.

5. Ignition Components Replacement

• Sub-step 1: Remove spark plugs and inspect for wear; replace if worn or fouled.
• Sub-step 2: Test ignition coils using a multimeter for proper resistance; replace if out of specification.
• Sub-step 3: Reassemble ignition components and ensure proper torque specifications are followed.
