I have a facelift dct elantra first thing it does sometimes not all the times when I accelerate then let off then try to accelerate the care falls feels like it breaks literally pushes u foward and it accelerates slow for the rest of the acceleration.second things is i always put the hand break on and sometimes when i turn the car on(just turning it on no handbreak removed or anything)the car jumps foward a bit and just don’t know if its normal or not.i know on the first one it’s lag but is it that bad?

How to removed? I try but i wasn’t able too
