❓ Frequently Asked Questions
How do I confirm cylinder 1 location on my engine?
Cylinder 1 is typically the front-most cylinder on inline engines and the front-right on V-engines. Check your service manual for your specific layout.
Should I replace all spark plugs or just cylinder 1?
If the plugs are near their service interval, replace all of them. It saves labor cost and prevents the others from failing shortly after.
Can a bad injector cause P0301?
Yes. A leaking injector floods the cylinder with too much fuel; a clogged injector starves it. Both cause misfires. Use an injector balance test to confirm.
