Vehicles using AEA engine list:

Engine AEA

Symptoms:
- Rough idling and occasional stalling
- Loss of power and poor acceleration
- Increased fuel consumption
- Engine misfires or hesitation during acceleration
- Check engine light illumination

Diagnosis:
- Inspect ignition components such as spark plugs, ignition coils, and wires for wear or damage
- Check for vacuum leaks in hoses and intake manifold gaskets
- Test fuel injectors for clogging or malfunction
- Examine the mass airflow sensor (MAF) and throttle body for dirt or faults
- Perform compression test to assess engine mechanical condition
- Scan engine control unit (ECU) for stored fault codes

Fixes:
- Replace worn or fouled spark plugs and faulty ignition coils
- Repair or replace cracked or leaking vacuum hoses and intake gaskets
- Clean or replace clogged fuel injectors to restore proper fuel delivery
- Clean MAF sensor and throttle body to ensure accurate air measurement and smooth throttle response
- Address any mechanical issues found during compression testing, such as valve or piston ring wear
- Reset ECU fault codes after repairs and verify resolution of issues

Prevention:
- Follow regular maintenance schedule including timely spark plug replacement and ignition system checks
- Use quality fuel and periodically add fuel system cleaner to prevent injector clogging
- Keep air intake system clean and replace air filters as recommended
- Avoid prolonged idling and aggressive driving to reduce engine stress
- Regularly inspect vacuum lines and intake components for leaks or damage
- Ensure timely oil changes with correct grade oil to maintain engine lubrication and longevity
