I have a 2001 Jeep Cherokee 4.0 I6. I live in Wisconsin and right now it is in the 30’s. When starting my Jeep cold (in morning or after work) the Jeep will run rough and misfire when cold. When I start driving it will be misfiring but if I pull over and turn it off and back on it will run fine no misfire. It has new plugs and I don’t think the coil pack is bad but if anyone has any way of diagnosing the coil or any information that could help.
