I have an F-3 that is running sluggish and sparks way too much when running. I want to change the rollers but have never done this before. Is there a video on youtube or somewhere else that would show me how to do this? Thanks in advance.

When was the last time you took the loco apart and lubed it? I doubt the rollers really need to be changed. I have a 2353 with fairly deep grooves in the rollers, and it runs just fine.
To lube a 2343, you have to take the motors off the trucks and lube the gears and bearings inside the trucks.
Since you have to go that far in be safe and inspect the brushes and springs. Might as well do a rather thorough inspection. I agree with servoguy that the rollers aren't likely to cause this.

Make sure that you also clean the wheels and rollers with either alcohol, or preferably naptha. You can use the naptha to clean everything inside and out, as it does not attack paint.
Do not lube the pick up rollers, just make sure they are clean, as well as the pin they roll on.

As suggested above, tear down the motors and replace the old grease in it.
I use "red-n-Tacky #2" grease in my rebuilds.
Clean out the brush holders, brushes and springs. On top of the armature, take a pencil eraser and clean the top copper surface where the brushes ride. Then clean out the grooves between the segments on the armature.
Also don't forget to check and clean your track. Dirty track will poor performance as well.
Good Luck!
I prefer 5W-20 motor oil for lube. I have used motor oil for 50 years and I know it never dries out or gets gummy. I don't have good experience with grease, 3 in 1 oil, light machine oil, WD-40, etc.
You can lube the pickup rollers. It will not affect their operation and they will probably last longer. I oil the commutators and it does not affect the electrical operation and reduces the friction.
