This only happens once in a while. Im pretty sure this is up to like 2500 rpm or so, the car feels like its almost bucking or something when i put on a decent amount of acceleration. My Tbird did the same thing and it ended up needing a major tune up. The car has trouble started sometimes, like it hesitates or something. Just not sure if this is the same exact thing or not cause when I got it inspected, the guy said everything looked fine. Any help would be awesome, thanks!

 

1. Throwing any codes????
2. You might have answered your own question...Tune up????
3. Look over everything for loose/worn/damaged connections....
4. Check fuel pressure....
5. Could be one thing or multiple things...

 

Agreed. It's likely fuel or spark which could be addressed with a tune up. Plug & Coil wires that are arcing or have deteriorated could cause that concern.
