Spark Plug Change - Clicking

01 XJ with the 4.0 I6. First before all this I seafoamed it earlier today. Then changed the plugs to autolites with .035 gap. As soon as I cranked it up, it was clicking. Flashing light indicated misfire correct? I've attached a video for someone with a good ear to hopefully watch. I have a very general understanding of different things it could be, just would like some extra pointers to help me work my way through the troubleshooting process.

Thank you for reading and watching

Sounds like one of the spark plug boots isn't seated on the plug all the way and is arcing to the block.

edit: and since you have an '01 that coil pack rail can be a real pain to get to seat on all the plugs.

Yeah tell me about it. Is there a trick to that? I couldn't figure out a good way to keep them all going down at the same time.

I usually start from the front of the block and move towards the back while pushing the coil rail down onto the plugs.
