Loping 4.0 with same in heater fan

[2005 wrangler X ?]

the other day I replaced my Blower Motor resistor
and noticed when on High and the next speed down I could hear the SAME loping sound that my engine has lower speeds "I" couldn't hear because of my ears

engine has had this loping since I bought it at 19,000 and now up to 42,000
Ive never tried to find out the loping cause as it runs great with no problems and no engine codes and never got worse ,,just a very,very slight lope maybe every 10-20 seconds
I had a mechanic friend of mine look at it months ago and he looked at me scratching his head and said it a "six"--Like that helped
and he knows his way around engines 50+ years from 12cly to lawn mowers, diesel and gas lol

any ideas out there?
thanks for any input

WELL it aint in a full JOG/shudder
(I was using my past of riding horses for an example, it aint walking and not jogging/ball busting just a nice full run)
is this better?
a very ,very,very slight vibration that comes and goes

Are we talking rpm flux, loping…initial thought is your alternator s rpm is loping with the engine. Which in turn is causing your voltage to vary and at the higher amp draw speeds the heater fan RPM is loping.

I'd guess I'd be looking at ODB live data and trying to correlate loping with something the engine/PCM is doing.

sorry Mac i havnt a clue as to what your saying---data-I assume a computer?
i do not have one for my jeep
But i do NOT have fluctuation in my interior lights or headlights at higher RPM's it does not increase but stil the same inconsistent lope
it is NOT a shake like a BAD or pulled plug wire its just a weird slight shudder at high RMP it doesnt ramp up but still the slight shudder/lope Off-trum
instead of a smooth thrum
I guess ill have to spend cash and have a shop? put a computer on it? I get NO codes

cheers

A $30 Bluetooth reader off Amazon and the torque light free app on your phone will read ODB live data.

Not everybody has a PHOOOOOONNE... Stand alone code readers are a thing!

Everyone has a smartphone. Find me a decent code reader for 25 to $30 that doesn't sell your soul to China and I'd be interested.

No - believe it or not, not everyone has a smartphone (nor wants one). $30 code reader + $1,200 PHOOOOOONNE doesn't add up.

Zero arguments there.

I bought this one that does not connect to my phone. it is "currently unavailable" but there a bunch of others like it on Amazon (and I'm sure other places): https://www.amazon.com/gp/product/B06ZYTDKP3/?tag=wranglerorg-20

I bought a "mid-range" unit from Harbor Bomber. Works well enough and no PHOOOOOONNE is needed nor wanted!
