I would look for an exhaust leak in the exhaust system or header, or a heat shield that is missing. Also check that the EGR valve function, (connections, heat tape, broken bolts). Check TPS sensor also.
Check the convoluted tubing (the split plastic tubing covering most wiring) for burns. You can buy a silicon tape that can be used to replace/fix it, but if there is an exhaust leak it will defeat most tapes except firesleeve.
If the coil is the problem, it may be exposed to an unwanted heat source as explained above.
