Hesitation upon light acceleration/ engine play?
I want to start off by saying Hi to everyone, i have been a lurker for a while now.
first im going to describe my truck. I have a 2010 f150 stx, 4.6l v8 2v. 1 Owner, this truck has never been wrecked, clean carfax. I bought the truck 3 weeks ago from a man that got disabled. (it sat up for a while...) It has 24000 miles on it. tires are dry rotting and i will be replaceing them this weekend. I have changed the oil, air filter, and cleaned the MAF sensor, and ran a bottle of gumout in 2 tank fillups, changed brakes and rotors so far... So now thats said. I will let you know about the problem im expeirencing.
No check engine light. Initially the problem was pretty noticiable, now i guess i would say its a "little" better but now really...
When i slightly hit the gas from a complete stop, i will get an initial hesitation for like a second and a half then after that truck runs normal, it shifts right and full throttle has alot of power. Now, if i step on the gas from a complete stop, there is no hesitation at all, its only when a lightly touch gas pedal from a red light etc.
The other problem that i find going on is when I come to a complete stop, RIGHT after the vehicle itself stops, there is a an engine shake, not a rough engine shake but its almost like the engine or something under the truck moves for a second, feels like its under my feet. The steering wheel does not move. Im trying to describe it as best as i can, It feels like something has play in it for a second or 2 right after my vehicle is completely stopped. I had the engine mounts checked... They are good.
Also the truck idles at 550 rpms and when i come to a hard stop, it dips about 100 below that, wasnt sure if thats normal or not, just mentioning it.
Thats my 2 problems im having if you guys have any questions or need more info or if i can explain it better please let me know. Thanks for taking the time to read this, ive learned alot on this site already.

Update, went to oreillys autoparts and they tested battery and they said it was bad..., dont have money for battery right this minute, but can a bad battery create these kinds of symptoms? I have no problems starting engine, it starts right up.
