Chrysler Repair: 1990 lebaron engine misses, coil wire, lebaron

Question
Hi Recently Roland told me to try changing the battery because of it missing. But that did not work. Changed the battery and still the same thing. It misses really bad when it gets to a certain temp. Then when it the temp levels out and stops climbing it will be perfectly fine. Was wondering if there is something else wrong. The only thing that came up for fault codes were 12 then 55. Thanks for your time.
