Was driving my 2.3 mustang 89 all of a sudden she started running rough and
hasnt cleared up changed evrything but the fuel pump what else am i miss
Hey Tony-It could be number of things. Is she rough at idle? When running at a certain speed? Spark plug wires/plugs changed? EGR? any check engine light on? Let me know some more detail so I can more accurately diagnose your issue. Ill monitor this post for a reply. Best of luck.
