My printer is an Ender 3 Pro. It's about 2 1/2 years old now. It has the 8 bit silent board.
It does not have the stock hot end.
It does not have the cloned stock replacement for the stock hot end.
The first one got dropped in the trash.
The second I threw as far as I could.
That lead to this saying of mine "If you clone a POS you should not be surprised if the clone is a POS."
My problem was constant plugs developing at the bottom of the bowden tube. The printer would start seriously under-extruding about 1 hour into every print.
I changed everything. Got the fancy Parker-Hannifin fittings for the bowden. Put in a 4015 ball bearing fan for the hot end. Built a baffle to make sure the fan air was directed at the heat exchanger. Drilled holes in the bracket to let the air out better. Nothing helped. Finally bought the Micro Swiss all-metal hot end. It isn't perfect but it does work. It is NOT a clone.
I mentioned the 8 bit silent board. The printer came with the noisy 1.1.4 board. I ordered the 1.1.5 silent board.
The first one to show up had a bad E stepper driver and consequently had built-in under-extrusion. There was no way to calibrate it. One day it would be 100 steps/mm and later the same day it would need to be set at 325. It would randomly change. It took 2 months to convince Creality that it was really the board. The replacement has been fine.
Post a gcode file that doesn't print correctly. Make it a small one (calibration cube, Benchy, etc) and I'll look at the E numbers and see what is going on. I have a little bit of moist PLA here that I could print it with if it comes to that.
The best trouble shooting tool is a project file. Load a model, set up to slice, and then use the "File | Save Project" command and post that file along with your gcode file.

So my problem seems to be Cura. I resliced with superslicer and everything is printing properly. Not sure what I have set wrong in Cura.
