So I recently bought a 95 Mustang 5.0 with a 5 speed at a public auction. When I got it, it wasn't running due to a bad fuel pump. Now I've already replaced the fuel pump and it's runs now but rough and shuts off sometimes however If i keep my foot off the gas then it's fine. I did notice that a cable that goes to the throttle is broken. Could this be the issue? If not then what?
