trying to keep it simple. when im at a stable speed or slowly picking up speed my car has a very faint hessitation. kinda of the same feeling as a large gust of wind is hitting the front of my car. all tune up stuff has been done.

coil and tfi are stock on a 188k+ car.

I'd say your well over normal range for TFI life. But as long as the car doesn't cut off or having starting troubles, yours might be functioning. Coil should be fine. Did you clean your throttlebody including the plate? Check your vacuum hoses for leaks. Whats your timing set at?
