On any vehicle, it is a timed calculation and measurement of exhaust gases and sensing knock(or predetonation) or no fire and sending that ibfo back to the computer. What this means: check your number 3 cylinder for spark out of the coil(replace as necessary) If spark exists, check the condition of the spark plug and replace as necessary with Motorcraft plugs. If all else fails, you may want to get this checked by a certified technician to verify a faulty fuel injector. Let me know if you wish to look at this further yourself and I will find instructions to help you out.
It can be issue with spark plugs or faulty spark plugs. Also
get the compression test done for cylinders. If any of cylinder shows low
compression then required, then that particular cylinder will cause misfire.
Also get obd codes scanned, the error code will let you know
which cylinder is misfiring or all cylinders are misfiring.
