Misfire Detected on Startup
The engine computer detected a misfire right after the engine started. This usually means the engine is running rough when cold, and it may be caused by ignition, fuel, air, or compression problems.
You may be able to drive short distances, but a misfire can get worse and may damage the catalytic converter. If the engine is shaking badly, flashing the check engine light, or stalling, do not keep driving.
P0316 is a generic powertrain code that indicates the PCM detected an engine misfire during the first 1,000 crankshaft revolutions after startup. This code often appears with or after a specific cylinder misfire code and can be triggered by conditions present only during cold start, such as weak ignition components, fuel delivery issues, vacuum leaks, or low compression.
It means the engine computer detected a misfire during the first 1,000 revolutions after startup.
No. P0300 means random or multiple misfires any time the engine is running. P0316 specifically points to a startup misfire.
Yes. Worn or fouled spark plugs are one of the most common causes.
It may disappear temporarily if the problem is intermittent, but the underlying fault usually returns until repaired.
Short trips may be possible, but it should be diagnosed soon because continued misfiring can damage the catalytic converter.
