Since I bought my car (about a month ago) it has had a stutter at around 4k. My car is an auto so I have to be on it for it to hit 4k lol. It hestitates a few times then revs out fine. Normal driving is fine. I have replaced fuel filter, plugs, air filter and cleaned my injectors. Anything else I should look for? I know I cant still do wires, cap, rotor and coil but i really don't just wanna throw parts at it. Any common issue that could be the culprit?

small intake leak could do that to your car...smoke test!

How does one perform smoke test? I'm done soapy water, spray bottle and carb cleaner.. never smoke...

You can have a shop do it for you or you can go to scottykilmer.com and find a cheap "cigar" method.

Maybe try a fuel filter. Theyre cheap and it probably needs replacing anyway.
