Check EGR valve, round thing located on the back of the head,about as big as a doughnut.
Sounds like a choke problem/fast idle speed adjustment.
Sounds to me like you need to replace the choke pull off.
Sounds like it could be low voltage Battery charged? Alternator working?
it sounds like your choke is not operating properly.
if its only on idle it sounds like a bad injector
Choke linkage holds the throttle cable for a higher idle speed while cold. When you step on gas after choke is warmed up the throttle cable is released from the little cam type plate that has steps on it and allows the the cable to return to t's normal position. Sounds like the idle is set too low.
It sounds like it is over fuelling. The auto choke may be stuck open? The ECU/AFM may be defective There may be a small leak in a fuel line.
It sounds like the Idle Air Control valve is bad. Could also be the Throttle Position Sensor.
Sounds like the idle valve needs adjusting, it's likely that the timings are out and needs adjusting which takes minutes to do. If the engine timing is not set around 700 - 950 rpm then it could be too low to support the engine to run. It's like having an automatic choke on older vehicles where you apply more choke till engine is warm enough
That sounds like high idle on the automatic choke, once the choke warms a bit it will kick down as it is doing.
inproper choke setting
It sounds like either a choke issue, or vapor lock. Good luck.
