Default 02 GT sputtering issue

I have an 02 GT manual. 110k miles. it starts fine. doesn't have any idle issues. it may pop (soft) or "putter" once in a while, but i drive normal. when I hit the gas harder it will sputter a lot, it will accelerate but not as it should. I was told spark plugs, the Coil over plugs, fuel filter, fuel treatment for the injectors. I was wondering what other people have thought or if they had this issue before. suggestions?

I do have a CEL, been on for years, since i did exhaust. its probably because it needs MIL eliminators, but i will do another ODB test.

Have you washed your engine bay lately? Maybe got some water under the coil packs. Have you cleaned your MAF sensor lately?

no didnt clean the MAF, haven washed the engine bay lately. however. I did do what I said and went back to get a test diag done. i am getting a P0316 code Misfire Startup 1000 revs. i researched this out and doesnt really say excatly what it is. but maybe someone of you guys seen this or had this before and what you did to fix this? i am still going to change the spark plugs. has been a while. other ideas? i will check the MAF sensor.

I want to say that the Motorcraft Plat plugs did the trick and the beast is running smooth and loud! they almost charged me for the motorcraft Copper ones. they were pricey. and not needed. thank you all for your help! greatly appreciated!
