View replacement guideQuestions that narrow it down
General checks. Answering them does not confirm the failed part on this vehicle.
Worth checking first
- A flashing check-engine light with a shake is a different path than a steady light with no drivability complaint.
- Do not treat a stall-while-driving report as a misfire unless the owner described misfire or uneven running.
Safety
When not to keep driving
- If the engine is shaking hard, a warning light is flashing, or you smell raw fuel, stop when it is safe. Continued misfire can damage the catalytic converter.
About the data
Counts come from replacement.guide aggregates for this model year. Component evidence comes from structured complaint categories and reviewed component mentions in complaint summaries. Owner-situation evidence comes from reviewed symptom language in complaint summaries. Reports are signals, not diagnoses.
How to read this page
PRIMARY components are the validated first-line associations for this job. RELATED components can be involved but are ranked after PRIMARY even when they have more reports. A report involving a component does not prove that component caused the problem.
