My truck broke down and we replaced ignition coil and it fired up and ran fine for a while, then started to sputter and check engine light came on and detected misfire in cyl. 1 and 2. We replaced cap, button, wires, and plugs and it still runs the same. We also replaced the crankshaft position sensor and that helped but still running a little ruff. When we pull the plug wires and ground them out to check the spark some of the wires are sparking more brighter than others. We have checked fuel pressure and all is well. I unplugged the coil wire after replacing the sensor and tested it with a volt meter, it is pulsing about 11.2 volts. Any ideas?
