Team,

I have read through the forum and done a lot of googling but I cannot find an answer for which cylinder is what number on the new engine.

I have a cylinder 1 misfire code on my 2014 Rubicon. So far I have replaced the spark plugs, ran a can of Seafoam through it and reflashed my tune. I was planning to replace the coil on cylinder 1 but I am now stuck. The driver side is a pin to work on so I do not want to keep trying out the next cylinder until the light clears. Has anyone figured out which cylinder is what number?

Swap the coil with another cylinder to see if the misfire follows. Also check all of your wiring for chaffing/rubbing while you're there.

This^^ usually the easiest thing to do. If the misfire moves from 1 to say 4 then the coil is bad.
