I'm really at a loss. It seems like what ever I think maybe the issue is not. I am thinking now it is some sort of seal leak. When the engine is cold initially it runs nicely for about a minute, then the random misfires occur, and stay until the engine reaches optimum temperature. Once the engine is allowed to cool, then the misfires come back, then goes away when the engine has reached the optimum temp. When the misfires occur, the engine is very sluggish to the point of stalling. Then once warm, the acceleration is normal, and so is the idle. I'm thinking intake manifold from the throttle body? My intake manifold is NOT plastic, but looks like cast alluminum. Is this gasket normally an issue or is it somewhere else?
