I may not be touch the volt tips to the correct places.

Here is what I did. Please let me know where I messed up.

1. Disconnected negative battery cable
2. Removed air cleaner hose
3. disconnected high-tension cord
4. disconnected electrical connector
5. where the electrical connector plugs into the coil pack, i used the two prongs from the volt meter to get a reading.


Any help is much appreciated.

Thanks

I am getting a recurring misfire on cylinder 2 where I have swapped plugs and replaced coil wires and the misfire remains. So can a bad coil pack on the other side cause this misfire since the plug wire connects adjacent to the coil pack. The reason I ask is bc the coil wire connects right next to the coil pack and it must connect to the ECU right there next to the coil pack.
