Hi. I have a Honda civic 2007. When i hit gas pedal little slowly, the car shakes , as if it lost little momentum (do not know exactly how to explain sorry). also when driving 40-50 km/ hour sometime it the car shakes, loses its speed (maybe) and the momentum. Whats the issue? I watched some videos, I feel like I can relate this issue to spark plug misfire.

Thank you.

 

Switch out the trans fluid for genuine Honda.
