What is the diagnostic code for a misfire?

Misfires that turn on the check engine light and log a cylinder-specific fault code are the easiest to diagnose.

Occasional misfires may pass unnoticed, but a steady misfire is hard to miss.

Why do I keep getting misfire codes on my cop?

Insufficient valve lash, a broken piston ring or a leaking cylinder head gasket can cause a partial loss of compression. Depending on where the vacuum leak is on the manifold, it can generate random or specific cylinder misfire codes.

(Same thing as a Mercury Villager) Was an O2 sensor code. Turned out the sensor itself was OK; there was just a broken wire coming out of the O2 sensor. I mended the wire and then disconnected the battery for a minute. Reconnected the battery. Started engine. Check engine light came on and stayed on. Disconnected battery for 10 minutes.
