new to forum. jeep liberty issue

[05jeepliberty]

Hey guys, new to the forum. I am having some issues with my 05 Jeep Liberty. I have been driving it daily for about 3 years and it's never really giving me any major problems I couldn't figure out until now. So about a month ago the radiator sprung a leak in the top driver corner and was spraying coolant out. I parked it until recently when I replaced the radiator and went for a drive. That's when it started running funny only well accelerating. The engine kind of sputters in and out for a moment then starts to clear up. The more acceleration the harder it does it. It seems like a fuel issue. I looked for a fuel filter and read some forums. Needles to say I just replaced the fuel pump assembly. And I am still having the same issue. I noticed however it seems to only do it once it warms up.
Where should I start next?

Coil packs got wet with coolant probably. Use compressed air to dry inside coil pack & top of spark plugs, see if that helps.
When was the last time you replaced the spark plugs? Change them every 30k miles anyways.
