Engine Misfire Detected - Cylinder 6
This code indicates a misfire in cylinder 6 of the engine.
Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.
What it means (plain English)
The computer notices that cylinder 6 isn't firing as it should. This means there's a problem with the combustion process in that cylinder, resulting in reduced power and increased emissions.
What the computer is actually seeing
The ECM measures crankshaft position and detects a deviation in rotation speed at intervals suggesting cylinder 6 is failing to fire. It may log a misfire count and possibly the duration of the counter readings for that cylinder.
What a healthy reading looks like
Normal misfire counts should be near 0 when the engine is running properly; counts above 20 in a specific timeframe usually trigger this fault.
Guided diagnostic — the DiagCoach way
Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.
- 11. Inspect the spark plug and wire for cylinder 6; replace if worn or damaged.
- 22. Check the fuel injector operation: use a noid light to verify the injector signal; if no signal, check wiring and connectors.
- 33. Perform a compression test on cylinder 6; check for values between 120-150 psi, replace if low.
Common causes
- Faulty spark plug or spark plug wire in cylinder 6
- Failed fuel injector in cylinder 6
- Low compression in cylinder 6

Frequently asked questions
Can I drive the vehicle with this code?
Yes, but expect poor performance and increased emissions. Fix it soon.
Will this code come back after clearing it?
If the underlying issue isn't resolved, it will likely return.
Why does this code pair with other cylinder misfire codes?
Multiple misfire codes can indicate a broader problem with the engine's combustion process or fuel system.
