Need some advice

So I ended up buying another jeep
94 Grand cherokee has the same motor as my red 88 Xj
4.0 I6, auto trans,
I see the 94 has 1 mechanical fan and no electric
so theres some differencs!!
I love it epecially the fact that it has the 4.0l

but unfortunately being that i worked on my cherrokee I can sense problems coming.....
with that being said
I want to start by getting 4 new tires, (totally irrelavent)
but when i make a turn and go tgo s tep on the gas
it hesitates a lil then it will accelerate

other then that i think its running really well for 147, XXX+ miles
anything someone suggest i should look at?
Thanks in advance!!

i forgot to mention! my radio will be on and then it shuts off the first bump i hit...
where would i start to fix something like tha!!!
