3. Exhaust Manifold Failure. Exhaust manifolds bolt up to the engine cylinders and the exhaust system. They transfer used engine air to the exhaust system where it is then released into the atmosphere. On the Triton 6.8, the bolts or studs that connect the manifold to the engine block are prone to rusting and failing.
A faulty EGR valve can cause a misfire all too often. It is usually caused by clogged passages inside your car’s intake. It will also diminish your vehicle’s power output. Oil vapors inside the engine increase carbon accumulation inside the exhaust gas recirculation valve, causing a stuck valve.
Exhaust Gas Recirculation (EGR) Valve. First, The Exhaust Gas Recirculation (EGR) Valve, is a mechanical device. And, just like valves and the throttle body, it can develop carbon buildup. And, most often that prevents it from, closing fully. When that happens, the (EGR) valve, allows exhaust flow at idle, which causes a rough engine idle
There are four key signs of a bad EGR cooler. White steam or smoke at the exhaust. Lowered coolant level with no leaks. External coolant leakage. Check engine light. If you notice any of these four problems, getting your vehicle checked out right. away is a good idea.GS5cvv2.
