Default Rough idel and it pops threw the snorkel now and again when i pull out

I have a 98 cherokee 4.0 that runs fine when its cold but after it warms up when i go to pull out sometimes it hesitates like its not getting fuel so i let off the pedal and get back on it itll pop threw the snorkel and itll run and idel fine for a few mins. I changed the plugs wires cap rotor injectors and its still doing it. No check engine light either idont know what else to do can anyone point me in the right direction?

No coil packs on the 98.

With your tune-up done and taken care of:
Have you ever replaced the CPS?

Have you done a bit of search on this problem yet?

Dozens of threads on this, to give you an idea about possible causes and how to approach fixing them.
