At the begining of the summer my car started acting up and wasn't running very strong. It would have no power off the line (starting slow or fast) and then sometimes all the power would be there...I asked some people and they said it was probably a vacuum leak. I didn't worry about it too much b/c I was going to do a top end rebuild at the end of summer anyways, which would involve replacing vacuum lines and such. Well, I finished the rebuild and it still has trouble...just tonight, the car broke loose off the line without me even pushing it, one min later it felt like an 80's civic that was in desperate need of a tune up (or worse). Any idea's what could be wrong or how I could figure it out?
