Studdering, Hesitation Need Help?
Ok, I believe I have narrowed down my hesitation, to happening around 1500rpms. I can be going about 60 in 4th reving at about 2500, and shift to 5th, and the rpms will drop to 1500, and that is when the studdering happens. Now if I go past that it calms down. So does this sound like what everyone else's. And what does it sound like is wrong? I have changed fuel filter, fuel pump, TPS, cleaned MAF. If you know please help. Thanks

Does you CEL come on? Mine did not. It did not show any codeswith the scanner either.
I had a fuel injection service done, too. Like everything else, it was fine for a few miles, then went back to the same problem.

To check COPs take out a plug, connect it to the cop, and touch the electrode against a ground point. Then watch for spark. And wear rubber gloves.
You can check injectors buy putting a stethoscope to them ($4 at harbor freight) and listen for ticking.

Ok, so basically I am just looking for the spark. I wasn't for sure if it was like checkingthe old spark plug wires. So the stethoscope thing, I just put it on the injector, with car running and listen for a tick. If it is ticking. is it good?

Right ticking is good.
One more thing make sure you disconnect that cylinder's injector when checking spark too. Then you can let the engine run with that cylinder dead as you check spark.
Then if you want you can swap that COP for another COP and so on to check all COPs
