- Hesitation or stumbling during acceleration
- Engine misfires or backfires
- Check engine light illumination (in later models with diagnostics)

Diagnosis:
- Inspect ignition components: spark plugs, ignition coil, distributor cap, and rotor for wear or damage
- Check fuel delivery system including fuel filter and carburetor or fuel injectors for clogging or malfunction
- Examine vacuum lines for leaks causing erratic idling
- Test the oxygen sensor and catalytic converter efficiency (for models equipped with catalyst)
- Perform compression test to rule out internal engine wear or valve issues
- Verify timing belt or chain condition and timing settings

Fixes:
- Replace worn or fouled spark plugs and ignition components to restore proper firing
- Clean or rebuild carburetor; replace clogged fuel filters; service fuel injectors if applicable
- Repair or replace cracked or disconnected vacuum hoses
- Replace faulty oxygen sensors and service catalytic converter if clogged or damaged
- Adjust ignition timing and replace timing belt/chain if worn or stretched
- Address any internal engine issues found during compression testing, such as valve adjustment or gasket replacement

Prevention:
- Regular maintenance including timely replacement of spark plugs, ignition parts, and fuel filters
- Use quality fuel and maintain the carburetor or fuel injection system clean
- Periodically inspect and replace vacuum hoses to prevent leaks
- Follow recommended service intervals for timing belt/chain replacement
- Monitor engine performance and address symptoms early to avoid catalytic converter damage
- Keep the cooling system in good condition to prevent overheating and engine damage
