Misfire issues on a 2001 Cherokee Sport
I have been dealing with misfire issues. At first I thought it was just the spark plugs so I changed those out and still got misfire problems. So then I changed the coil pack and still have the same misfire problems. Any thoughts on what is going on?

First pull codes. See what's going on. Rather than keep throwing parts at it, run to your local parts store and pull the codes if you can. If it's OBD1, do the key trick and read the codes.
While youre there, pick up a Compression tester and/or Leakdown tester on rent. Perform the tests. Post the data. Otherwise you'll be throwing parts at it or running through all the various sensors, pulling them, then cleaning them.
If you know know how to verify spark, that's a great first step. I assume you know the firing order and location of "#1" on distributer.
