Hi i have been having a problem with me civic since i bought it sometimes when i accelerate from a stop it feels like something hits my car. The main time it seems to feel like a hit on my car is when im braking when im coming up to a red light then the light changes green and i push the accelerator and it feels like a big hit only once then its runs fine. How much i push the accelerator doesn't matter cause it stills hits then it accelerates good i really don't understand why it does it. The car kinda shifts a little hard compared to other cars i have had and im not sure if its the transmission cause i changed it out for a used one and it did the exact same thing.
thanks and i appreciate the help
