Update.
Well, couldn't swap on 1993 SSp's coil. Somehow the tip got busted off the coil plug, so i couldn't use it. Unfortunately i found this out after spending 30 mins getting the old coil out.
I used this website, which gave the following procedure to test the coil
TFI TESTING
So i'll be doing that this afternoon. I didn't have a meter with me when i was with the car yesterday
So, i tested the resistances of the TFI and 2 other TFI's i got at the boneyard. My TFI is an A1A type...so i assume it's 21-years old and original. The junkyard TFI i got was an A2A module, so i assume it's newer. I also found a parts store TFI on an '86 GT at the yard.
So, i compared to given values from the website above
The aftermarket TFI's numbers are WAY off and significantly lower.
So, i assume if the module was bad, some of these resistance numbers would be way off? I'm kinda thinking of going to advanced...testing the A2A module and trying that out on my car.
I drove the car Sat after cleaning the Accell coil up and reinstalling it. The hesitation above 4000RPM is still there. I watched the tach and it doesn't jump or dance around at all. The car just feels like when it hits 4000, it hesitates, then goes, or hesitates completely to redline. It's def losing some power up top.
I watched my FP gauge and it stayed steady.
PS. The car has never stalled on me nor shut off when it gets hot...so i don't have the normal TFI symptoms. There are no metal shavings or anything inside the dizzy

TFI TESTING
We should now test the coil. Use an ohm meter and probe the resistance of the teo small terminals, and you should find 0.3 to 1.0 ohm. If the resistance is not ok, it may be a bad coil. If the resistance is ok, probe one small terminal and the coil wire terminal. Resistance should be 8000 to 11,500 ohms. If the resistance is not ok, replace coil. If the resistance is ok, go to step 5.

So the two motorcraft TFI's i have are higher than the given test values, and the A2A module is slightly lower in resistance than the module on my car.TFI RESISTANCE Terminals to jump Resistance (OHMS)
