What is your question?
My 4.0 engine in my Cherokee was running rough, and engine light came on. Put new plugs and it still ran rough. Reset code over and over till light wouldn't go off. Put in new ignition coil pack today. Still runs rough and light came back on. Did I mess the plug(s) running with the bad coil ? What can I do to fix this issue ? Thanks
