MilesFox Posted October 27, 2013 Share Posted October 27, 2013 (edited) Is it a misfire or a stumble. I ended up swapping all of the components on mine to figure out the sparkplug wires were shot. It would only misfire under load, but idle fine, and cruise fine until adding more load. This triggered the check engine lite for cyl misfire, and would flash while actively misfiring.
