Ok so I have an 02 / 3.0 / manual trans. Started misfiring on cylinder 5 recently.
As the problem progressed, I noticed the speedometers bouncing up to maximum speed and the odometer whirring by. This was accompanied with an engine code that said I was going too fast/ revving too high.
After playing with the coil, plugs, wires, I had an epiphany. If I was "going 120", the speed limited would be kicking in. Unplugged the speed sensor in the trans, my problems evaporated. Apparently, when the speed limiter kicks in doing 30mph, it makes the truck run Rough!
