Hard to tell anything from that video but things to check are of course the pan on the bottom of the intake manifold. The other thing I've found is the wires for the coolant temp sensor behind the thermostat housing will get dry, brittle and flake the insulation off and the wires will short together. When that happens the PCM will see the coolant temp as -40* so it richens the fuel mixture a bunch. This and also a thermostat that is stuck partially open will run the adaptive fuel mixture way rich. So even after you fix these problems you need to clear the adaptive memory by removing the positive battery cable from the battery. Touch the removed cable to the battery negative terminal and hold it for 30 seconds. This does a cap discharge and the learning process will start over so it may not idle well at first. Cycle the engine on and off a few times then drive it for awhile so it can relearn.
