Thanks in advance.... while driving if I am just holding the pedal down and going like 50 the car feels like it is going from 51mph to 49mph but i am not moving my foot on the pedal what so ever does anyone have any clue what this could be almost feels like a big gust of wind but there is no wind just started to notice this issue in the last month all service done at acura allways every service done car has 130k miles 05 tl also happens at other speeds but just trying to explain...

 

A possibility would be the APP sensor. It is located under the hood on the passenger side rear corner under a plastic cover. You can find it easily as there is a black throttle cable going to it that runs along the upper firewall. Apparently it's pretty common for these to go bad and it can cause weird throttle issues and sometimes without throwing a check engine light. You will find a ton of info on this sensor with a search. It's easy to swap and relatively cheap.
