- Scan for error codes related to oxygen sensors or engine management system

Fixes:
- Replace worn or fouled spark plugs and ignition wires to restore proper spark
- Repair or replace cracked or leaking vacuum hoses to eliminate air leaks

- Regularly service air filter and fuel filter to maintain optimal engine performance

Prevention:
- Follow recommended maintenance schedule for ignition system and timing belt replacement intervals

- Periodically inspect vacuum lines and intake components for signs of wear or leaks
- Avoid prolonged idling and ensure engine reaches operating temperature before heavy acceleration
- Keep engine management sensors clean and functional to prevent drivability issues
