Jeep Information

My jeep is a 2001 grand cherokee with the 4.7l and had been running perfectly fine until yesterday after work I went to start it and it barely fired. It had loss of power, hesitated and stalled at stop signs and had a shake and what appeared to be a knock. When I got home I did the key turn thing to see the codes and it gave me a p0301 which is a cylinder 1 misfire. Got to toying around on it swapping coil packs and spark plugs and nothing changed while doing this I got new codesp0353, 352, 351. This morning I reset the computer and have a totally new code p0301. Messed around with unplugging injectors and still no change. I'm stuck and stressed out and need some help bad.
