The P0316 code on your Ford means the engine has detected a misfire within the first 1,000 revolutions of startup. I had this problem on my 2014 Ford F-150, and it was causing the engine to run rough for the first minute or so before smoothing out. This issue is usually related to ignition or fuel delivery problems.
Start by checking the spark plugs. Worn or fouled plugs are a common cause of misfires, especially during startup when the engine is cold. If the plugs look dirty or damaged, replace them with new ones. While you’re at it, inspect the ignition coils for signs of wear. If one of the coils is failing, it can cause a misfire.
If the ignition system seems fine, move on to the fuel injectors. A clogged or malfunctioning fuel injector can cause the engine to misfire when starting. Cleaning the injectors or replacing a faulty injector should fix the problem. It’s also worth checking the fuel pressure to make sure the fuel pump is delivering the right amount of fuel to the engine.
Finally, inspect for vacuum leaks or a faulty Mass Air Flow (MAF) sensor, as these can also cause a misfire on startup by disrupting the air-fuel mixture. Use a smoke test to find leaks and clean or replace the MAF sensor if needed.
Once you’ve made the necessary repairs, clear the P0316 code using an OBD-II scanner and test the vehicle to ensure the misfire has been resolved. If the code comes back, you may need to perform further diagnostics, but in most cases, addressing the spark plugs, coils, and fuel injectors will fix the issue.
