Bill Fulton presents this tip clip video on what would seem to be a basic, simple problem. A 2.4 liter Toyota in a Toyota Tacoma pickup truck with an intermittent misfire under load. You can feel a slight hiccup, jerking, bucking type sensation and know there are a lot of things that could create that problem– dirty injectors, contaminated mass airflow sensor, lean density misfire, excess of EGR, secondary ignition problem. Watch to find out.
