I have a 1999 mustang 3.8L engine. The check engine light went on. The code PO411 pulled up. My friend looked at engine, can't find the item its saying the problem is. Just two weeks ago, a mechanic replaced the wiring that was burned on the engine. Help

Check the secondary air hoses for damage, wear or poor connections and let me know how they look.
