P0301 through P0310 - Misfire Detection Monitor The misfire detection monitor is designed to monitor engine misfire and identify the specific cylinder in which the misfire has occurred. Misfire is defined as lack of combustion in a cylinder due to absence of spark, poor fuel metering, poor compression, or any other cause. Ignition system
Running out of fuel
EVAP canister purge valve
Evaporative emission system
The MIL will blink once per second when a misfire is detected severe enough to cause catalyst damage. If the MIL is on steady state, due to a misfire, this will indicate the threshold for emissions was exceeded and cause the vehicle to fail an inspection and maintenance tailpipe test.
Problem car is 2000 ZTS, Zetec, 136k miles. Has new fuel filter.
Ok so I finally got a CEL after a month of the car bogging, lack of power, etc. I did not drive the car much, mainly just to test drives after I replaced the ignition coil and the fuel filter.
So now that I know the code, P0301 - Cylinder 1 misfire, where do I start looking? I have new spark plugs that I have been too lazy to put jn, but will as soon as I find my gapper. After that would the injectors be a likely cause?
