So I bought a 2000 Cherokee SE about a week ago. It had no check engine light at the time of purchase and drove/ran like a dream. After driving it about 150~ miles, the check engine light comes on with an EVAP Leak. I figured it’s not too big of a deal and I’ll figure it out eventually.

After driving another 20 or so miles, I get a misfire in Cylinder 2. Seeing as I just bought it and didn’t give it new spark plugs yet, I figured I’d start there. So after replacing all my plugs and sitting the coil rail (can’t remember the exact name of it) back on the plugs and bolting it back down, I clear the codes and fire it up. I now have a misfire on both Cylinder 2 and now Cylinder 5.

I know that the grouping on the coil rail (again, not sure that that’s the exact name) has Cylinders 2 and 5 together so I’m suspicious that but I’m also new to XJs and would like any advice or suggestions.
