Hi all i know this is my first post so i would like to say hello to you all.I have a 52 civic type r and it seem to have a very slight missfire/hesitantcy and low speeds.It occurs when changing gear at low revs.when you accelerate it initially seems to missfire/hesitate then go.It is fine at higher speeds and hits v tec fine.i had the car serviced 2 thousand miles ago and the only mod on the car is a custom rear box.I need to get this sorted asap as im going to the ring in a few weeks.any advice would be great.
