Thats what I figured, I already did it with one of the wires.
What do you think it could be then? All ignition parts are new.

Usually the scanner is a big help in diagnoses. Can you do a screen recording of it idling, maybe giving throttle, shifting through gears and stuff? Something may stand out?
Ill try, Ive watched at idle and it all seems pretty usual, the tach does bounce a bit when it misfires though.
I've mentioned before as well that you can leave your phone's mic on or off. I like to leave it on when I want to take verbal notes to coincide with what I'm doing in the truck if that makes sense.
Usually useful when driving around. Like " I'm at a light, I'm taking off, just felt a miss....then I can look back at video and get in the ballpark of where in the timeline I should focus on more or less....
Alright I havent had time to screen record as I have been working, but today the truck drove terrible, awful idle bouncing up and down like it wanted to die, absolutely zero power at all, constant misfire at idle. Im gonna check to see if I can tighten my spark plug wites a bit maybe that will help with idle mis.
It's not the plug wires being not tight enough. They could be a quarter-inch away from the plug terminal and still fire the plug.
Something more is wrong.

Do you have any idea what it could be reading through what I have done? CTS is new too and tested good
Ok so I got a video, I just gotta make a link so it can be viewed. The truck is still misfiring when idling hot. I noticed if I lightly rev when in park the truck almost hesitates to rev, like it raises slightly in rpm then drops even if I hold my foot. If i rev up higher then let up it makes a almost thoomp sounding sound and crackles, might be normal because I have a loud exhaust. But yeah the truck sits around 200s according to 02 sensor, any help is greatly appreciated.

This is after a long hot drive with some serious hard throttling at times. I was barely holding my foot on the gas at 700 rpm which the truck did not like and it shook pretty good. Thats what the data read. Pretty sure the knock counts are just bogus.
Whats also bizarre that I forgot to mention is earlier the truck decided to kick up out of nowhere while i was passing someone and was wayyyy faster like how it used to be, then at the next light was the exact same as before.
