Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, multimeter, fuel pressure gauge.
Disconnect the negative battery terminal to prevent electrical shorts while working on the vehicle.

2. Address Ignition Components

Sub-steps:
1. Remove the engine cover (if applicable) using the socket set.
2. Inspect and replace spark plugs if they show signs of wear (gaps larger than specified, carbon buildup).
  - Torque Specification: Tighten to manufacturer specifications (usually around 13-15 lb-ft).
3. Check ignition coils for proper operation using a multimeter; replace any faulty coils.

3. Inspect Fuel System

Sub-steps:
1. Connect a fuel pressure gauge to the fuel rail.
2. Turn the ignition on (do not start the engine) and check for fuel pressure against the manufacturer's specifications.
3. If pressure is low, inspect the fuel pump and fuel filter for clogs or failures; replace as necessary.

4. Check Air Intake System

Sub-steps:
1. Inspect the air filter and replace if dirty or clogged.
2. Check for any cracks or loose connections in the intake hoses or throttle body.
3. Clean the throttle body using appropriate cleaner to remove any carbon buildup.

5. Verify Exhaust System

Sub-steps:
1. Visually inspect the exhaust system for leaks or damage.
2. Check for a clogged catalytic converter or muffler by performing a backpressure test.
  - If blocked, replacement of the catalytic converter may be necessary.
