When trying to start the car, its a little difficult. It like to spit and sputter for a bit and sometimes takes a few tries. Once it stops sputtering it'll rev up a bit before dropping back to idle. When you give it gas as to rev it hesitates and drops off before revving. Acceleration is poor from the hesitation.
