What would cause a random misfire code?

A random misfire code usually means the air/fuel mixture is running lean. But the cause might be anything from a hard-to-find vacuum leak to dirty fuel injectors, low fuel pressure, a weak ignition coil, bad plug wires, or compression problems. Even a dirty MAF sensor can cause a lean code and/or misfire to occur.

What does a misfire feel like at idle?

You may also feel intermittent jerking, bucking, or stumbling from the engine. You’ll notice rough and/or slow acceleration. Vibration while the vehicle is running is common especially if the misfire is caused by a mechanical problem. The severity varies depending on the RPM and is often worse at idle.

Fortunately, Ford finally redesigned the spark plug in 2009. Vehicle models from 2009 on do not use the original design.

Can a bad o2 sensor cause a random misfire code?

If an oxygen sensor or mass airflow sensor is failing, it could give incorrect data to your engine’s computer, causing the misfire. When a vacuum line is broken, it can cause a fuel-injected motor to misfire.

What is the diagnostic code for a misfire?

Misfires that turn on the check engine light and log a cylinder-specific fault code are the easiest to diagnose. A flashing check engine light and a P0301 to P0312 diagnostic trouble code (DTC) is a surefire indication that one or more cylinders are misfiring. Occasional misfires may pass unnoticed, but a steady misfire is hard to miss.

What are the different types of engine misfires?

Type “A” misfires are indicated by a flashing orange “Check Engine” light (CEL), while Type “B” misfires simply illuminate the CEL. Both types of misfires will store a P0300-series diagnostic trouble code (DTC) in the diagnostic memory.
