While you can drive short distances, avoid extended driving or high RPMs. The misfire can damage your catalytic converter and reduce fuel economy. Address the issue promptly to prevent more expensive repairs.

Q: What causes P0316 only during startup?

Startup misfires often result from weak spark plugs, failing ignition coils, or fuel delivery issues. Cold engines require richer fuel mixtures and stronger spark, so marginal components may only fail during this demanding period.

DIY repairs range from $50-200 for spark plugs and basic maintenance to $300-600 for ignition coils or fuel system components. Professional repairs can cost $200-800 depending on the root cause and required parts.

Q: Will P0316 cause my car to fail emissions testing?

Yes, P0316 will likely cause emissions test failure. Misfiring engines produce higher emissions and the stored code itself is often an automatic fail. Fix the misfire before attempting emissions testing.
