I bought this truck from my boss man and had it put in the shop to replace the head gasket but they ended up changing the valve cover the intake manifold gasket and putting plugs in it due to a smoking issue and skipping but after all the repairs were done it turns out that the valves are bad in the engine and they more than likely they were bad when they installed originally. It's causing stalling issues in traffic and I'm sure I'm not the only one with this problem.
