Misfire - Engine Miss
Check Engine Light Step 2 - If no service light is triggered with a steady misfire, use an infrared thermo gun to test the exhaust temperature of each cylinder.
Infrared Temperature Meter
Exhaust Temperature Step 4 - If no results are yet gleaned, start the engine and allow to idle, remove the fuel injector electrical connector on each cylinder one at a time while observing the engine performance, if no change is observed at a particular cylinder, the misfiring cylinder has been located.
Fuel Injector Wire Removed Step 5 - This can also be achieved by removing a coil wire connector (COP systems only - no plug wire attached ).
