A flashing check engine light and shaking car indicates your engine is misfiring. This dangerous condition requires immediate attention to prevent catastrophic damage.

In this DIY repair tutorial, we examine the most common causes of misfires that trigger the check engine light to flash:

Faulty fuel injectors that fail to properly spray atomized fuel into the cylinders
Damaged ignition coils that don't generate adequate voltage for the spark plugs
Fouled or damaged spark plugs unable to ignite the air/fuel mixture
Defective variable valve timing components like the cam phaser
Bad MAF, O2, CKP and camshaft sensors providing inaccurate data to the ECU
Vacuum leaks introducing unmetered air and disrupting combustion
Stuck open EGR and EVAP valves skewing the air/fuel ratio
Driving with persistent misfires can severely damage engine components like the catalytic converter and oxygen sensors.

Using an OBD2 scanner to diagnose the trouble codes is the first step. Then inspect and replace any damaged fuel injectors, ignition coils, spark plugs, sensors or emissions components.

Addressing the root cause promptly can restore smooth performance and prevent expensive repairs.
