- Test fuel pressure and injector operation
- Examine timing chain tensioner and camshaft timing for irregularities
- Verify cleanliness and operation of the intake manifold and throttle body

Fixes:
- Replace faulty ignition coils or spark plugs to restore proper combustion
- Repair or replace leaking vacuum hoses to eliminate rough running
- Clean or replace clogged fuel injectors to improve fuel delivery
- Adjust or replace timing chain tensioner if timing irregularities are found
- Clean throttle body and intake manifold to prevent airflow restrictions
- Reset the ECU after repairs to clear fault codes and relearn parameters

Prevention:
- Follow regular maintenance schedule including timely spark plug and air filter changes
- Use quality fuel to avoid injector clogging and carbon buildup
