Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Address Ignition System Issues

Tools Required: Socket set, torque wrench, spark plug socket, multimeter.
Remove the engine cover if applicable.
Disconnect the battery (negative terminal).
Remove spark plugs using a spark plug socket; inspect for wear, carbon buildup, or damage.
Replace faulty spark plugs with OEM equivalents, ensuring they are gapped correctly (refer to manual specifications).
Reinstall spark plugs and torque to manufacturer specifications.

3. Inspect Fuel System

Tools Required: Fuel pressure gauge, basic hand tools.
Locate the fuel pump fuse and relay; inspect and test for functionality.
Connect a fuel pressure gauge to the fuel rail; turn on the ignition (do not start) to check for proper fuel pressure.
If pressure is low, replace the fuel pump or check for clogged fuel filters.
Inspect fuel injectors for proper operation; clean or replace if necessary.

4. Examine Air Intake and Exhaust Systems

Tools Required: Basic hand tools, vacuum gauge (optional).
Inspect the air filter and replace if dirty or clogged.
Check the intake hoses for cracks or leaks and replace as necessary.
Examine the exhaust system from the catalytic converter to the tailpipe for blockages, leaks, or damage.
