OK.. i now know that my speed sensor is not working.. and i have my car on limp mode(Vtec does not want to work) .. i purchased another speed sensor.. and waiting for it to be delivered to me.. i know my mechanic hands can do pretty much anything on my prelude.. but never have done a speed sensor hange.. if anyone has any experience.. is it easy to change out by myself.. or is it recommended to get a near by shop to do it for me...? i need opinions..

if it is easy to bolt off and on.. can you tell me where it is located and how to change it.. thanks
