I got my car to start finally and now it idles fine but when you go down the road and floor it all it does is make more noise (not bad noise) and not speed up if anything it slows down but at part throttle its fine. Now my question is, is this a timing issue or I also just put a blox manifold on and I just now remembered there was a extra vacum port on the back could this cause this or something else to do with the manifold? Just wondering where I should start first.
