Failing coil replaced, car runs up to redline with no issues anymore!

Wanted to share some additional perspective on this:

Cel started coming on more frequently during daily driving, 6000 rpm would activate it.

Gas mileage had dropped to below 23 mpg average

Car would hesitate and sputter (stalled once) as you pulled to a stop and seemed sluggish in general.

Strange fuel smell in the cabin especially with the fan on high. Possibly unburned fuel??

During the couple sessions that I ran with the cel there was a profound change in the traction / stability control. I had turned it off with the 5 second switch but it was really nuts whenever I had high rpm high g load corners. Motor cut and rear brakes grabbed to the extent that I nearly lost it.

With the new coil, all of these street issues are gone and it feels like I am running the E85 tune compared to how the car was running up till now. The power difference is enough to tell the difference. Even the exhaust note standing outside the car at idle sounds different.

It would appear that when a coil gets this bad, there are multiple symptoms present even if the cel is intermittent.
