Exclamation 93 Yj Hard starting and no low end power

Hi! Ive been having trouble with my Jeep lately. It's a 93 YJ 6cyl. 4.0 HO. I was driving, and when I went over bumps it would sputter and sometimes shut off. I reconnected all the wires in my harness, put on a new ignition coil, and this seemed to fix that problem. then it started doing it again. I checked the codes, which told me to replace the O2 sensor, and MAT sensor, which I did. Now it takes forever to start. It cranks forever before it stats, and when I'm driving it has no low end power. It sputters and backfires, and just wont go when I'm going up any hill or when I try to pull out quickly. On hills where I used to easily get 65 miles an hour, it now struggles to reach 35. I also replaced the fuel filter, and it is showing codes 33, 23, and 21. Please help!!
