2001 4L Sputtering

PROBLEM WITH MY 2001 JEEP CHEROKEE Limited 4.0L
2 WHEEL DRIVE ABOUT 72K MILES
AS I WAS LEAVING FOR WORK TONIGHT, I STARTED UP MY JEEP AND IT STARTED MAKING A SPUTTERING NOISE.
I DROVE DOWN THE STREET A LITTLE WAYS AND IT WAS BUCKING AND HESITATING. THE CHECK ENGINE LIGHT CAME ON AND STARTED FLASHING. I PULLED OVER AND TURNED OFF THE ENGINE AND WAITED A FEW MINUTES.
I STARTED THE ENGINE AND IT DROVE FINE, THE ENGINE LIGHT WAS STILL ON. I GOT ON THE HIGHWAY AND GOT UP TO ABOUT 85 WITH NO PROBLEMS.

WHEN I GOT HOME I STAYED THERE FOR ABOUT 45 MINUTES, AND THEN I WENT OUT TO THE STORE, INITIALLY IT DROVE FINE, PUT ON THE WAY BACK IT STARTED AGAIN.
IT SPUTTERS AND HESITATES, WHEN I STEP ON THE GAS IT FALLS ON ITS FACE FOR A SECOND AND THEN IT TAKES OFF.
IT I FLOOR IT , IT WILL SPUTTER AND THEN ITS FINE?

ANY IDEAS?

Replaced coil pack and ran great for a few days, then started acting up again.

what are the code(s) it's giving you?

You can check the codes yourself, by turning the key to on 3 times, but not all the way to START. (off-on-off-on-off-on) It will show any codes it's giving on the odometer, and say d0nE when it's finished.

Write down any codes it gives you, turn off caps lock, and report back what you find.
