Ok I have a 00 Civic SI and last week I was on my way home and the service engine lights came on and it started acting funny like gettin kinda jumpy or something... But anyways I took it to auto zone the next day and had it scanned and it said multiple cylinder misfire.. Well I changed the plugs, wires, coil, and that didnt help its still doin the same thing.. So I took it to a local mechanic shop and he said it had no compression that he would have to pull the head off and go from there. So wat do you guys think?? I really didnt wanna spend all my christmas money on head work or a new motor, its just my daily driver....Please help
