Misfire, Cylinder 4
Had a CEL with a code of Misfire on Cylinder 4. Replaced the Spark Plug, Tube and Connector. Still misfiring at higher gears when I "punch it".
What else could it be? The Coil itself? The Wires? What would you do? |

Probably the coil, you could do the poor mans test and change the coil to a different cylinder to see if the new cylinder gets a misfire. Then you'll know it is the coil and not something else.
