I use torque lite cause I'm too cheap to pay for the app, I haven't even seen where it'll show misfire. I think I have one when I first start the truck and accelerate in first but it'll go away when it warms up. I plan on doing a complete plug, coil and wire change just to know that's been done as I'm the second owner and doubt the previous owner did it ever.

I'm just suggesting a different thought direction.
What you spend on guessing by throwing parts like this could be better invested to get the program, use it, then know what your chasing over just a feeling that may not pan out.
Said another way, it's diagnostics first then repairs.
Good luck..

Ok, test 53 will show the stored counts as along as you don't do a clear function.
If a clear is done, several drive cycles may be needed to get a count that is worthwhile and shows a pattern.
This history location does not set a code as it was not given that ability in software.
This history is valuable for picking out what cylinder is causing a misfire under certain conditions such as in OD and light throttle that comes and goes.
Most often this is a faulty coil with 'shorted' turns in it's winding but still works at producing a lower voltage output hence is not a hard failure that produces a misfire code..
Lastly, zero counts is the perfect situation, however no engine will run free of misfire counts all the time due to changing conditions so look for a pattern on a repeated basis over time. This can even suggest a problem or future failure of one cylinder such as the coil or it's boot is leaking from a pin hole or moisture in the plug well.
Like a good Doctor with knowledge and tools to work with, to fix you up.
Your outside and have to look through a window to see what's happening inside.
Good luck.

BLuegrass, i had high misfire counts on cylinder 5, plug is good and tight, and no moisture in plug well, so i relpaced the coil with an OEM. I keep 3 oem coils in my door pocket...just for special ocassions like this one...lol Ill have to clear the history and run it for a few weeks
