2001 2.5 L Rough Idle and Loud Metal Knocking??
My 2001 2.5 L Ford Ranger 5 spd manual with 143,000 miles is having a serious problem. It's idling very rough (~500 rpm) and putters but never dies, it seems okay at higher rpms but only under no load, in neutral. Once I put in in gear and drive there is a very loud metal on metal knocking/hammering sound! I mean loud!
Not really sure what this is?? This is my second ranger and I have never heard a sound like this before. It is coming from the engine and not from a loose exhuast part, the noise seems to be in sync with aceleration. No codes thrown, no vacuum leaks, no air flow problems, juice flowing to plugs. Any ideas??
