Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery to prevent any electrical issues during the repair.
Gather necessary tools and parts.

2. Address Fuel System Issues

Sub-steps:
1. Inspect the fuel pump fuse and relay; replace if faulty.
2. Check the fuel filter for clogs; replace if necessary.
3. If the fuel pump is suspected, test the fuel pressure with a fuel pressure gauge and replace if below specifications.

3. Clean or Replace Air Intake Components

Sub-steps:
1. Remove the air intake duct and inspect the air filter; clean or replace if dirty.
2. Check for any obstructions in the intake manifold.
3. Clean the throttle body using throttle body cleaner and a soft cloth.

4. Repair Ignition System Components

Sub-steps:
1. Remove the spark plugs and inspect their condition; replace if worn or fouled.
2. Test the ignition coils for proper resistance; replace if out of specifications.
3. Reinstall spark plugs with the correct torque (typically 13-15 ft-lbs).

5. Inspect Exhaust System

Sub-steps:
1. Visually inspect the exhaust system for any visible damage or leaks.
2. Check the catalytic converter for signs of blockage; replace if restricted.
3. Ensure all exhaust connections are tight and leak-free.
