Solution

1. Preparation

• Gather tools and parts required for the repair.
• Ensure vehicle is parked on a flat surface and the engine is cool.
• Disconnect the negative battery terminal to prevent electrical shock.

2. Replace Spark Plugs

• Tools Required: Socket set, torque wrench, spark plug socket.
• Remove engine cover (if applicable).
• Use the spark plug socket to remove old spark plugs.
• Inspect the gap on new spark plugs as per manufacturer specifications and adjust if necessary.
• Install new spark plugs, tightening them to the specified torque (usually around 13-15 lb-ft for most models).

3. Inspect and Replace Ignition Coils

• Tools Required: Socket set, multimeter.
• Remove the ignition coils by unscrewing them from the cylinder head.
• Test each ignition coil with a multimeter to ensure they are within the manufacturer’s resistance specifications.
• Replace any faulty ignition coils with new ones, securing them in place.

4. Clean or Replace Fuel Injectors

• Tools Required: Fuel injector cleaning kit (if cleaning), or replacement injectors.
• Remove fuel rail and disconnect fuel injectors.
• If cleaning, follow the kit instructions to clean injectors; if replacing, install new injectors.
• Ensure all connections are secure and reattach the fuel rail.

5. Inspect Vacuum Lines and Intake Manifold

• Visually inspect all vacuum lines for cracks or disconnections.
• Replace any damaged vacuum lines.
• Check the intake manifold gasket for leaks and replace if necessary.

6. Test Engine Compression

• Tools Required: Compression tester.
• Remove spark plugs and insert the compression tester into each cylinder.
• Crank the engine and record compression readings; compare with manufacturer specifications.
• Address any low compression readings by diagnosing further issues.
