Replacing spark plugs and coil boots on a 2016 dodge journey. Filmed it using the cinematic mode on my iphone 13, it did not focus correctly. Used NGK platinum plugs 7098 and coil boot kit 90069 Duralast brand.
Those first three connectors on the three ignition coils don't have to be unplugged, coil can be removed with them still connected it's the last one that needs to be unplugged because there really is no space for you to remove the coil with the connector still connected.
I would double check the gap on the spark plug. Sometimes if it drops down when installing it will throw the gap off. Double check the coil plug to make sure it’s producing spark and be sure the electrical connector is ok. Could also be a problem with the injector not working on that cylinder. Lastly if it comes down to it if you know how to do a compression test on that cylinder to see if there might be a mechanical issue affecting that cylinder.
