Loosing power intermittently


after a 15 minute daytime cruising, I punch it (from 65 and up) and no response. But, I could still cruise even after, just can't produce a kickdown.
From a stop, the car crawls slowly ( even with a heavy foot on the throttle) and then gets going. I'm not sure if this would happen during a cold morning start. I still have to find out. My guess is TPS.
I've also recently changed coolant.


I just disconnected the battery and will let it sit for awhile.
I also have vibration issues that come and go especially during my early morning commute (45-65). I think my car needs an general annual checkup
(Coolants, suspension, fluids, brakes,etc.).
