it does sound like it could be the auto choke. because if it only happens while engine warms up. whats it like when you rev it from cold at stand still?
The likely cause is fuel starvation, possibly caused by the injectors. Were they causing overfueling the electronics would complain, as emissions would increase. If underfueling is the problem, caused by the injectors or fuel pumps, the electronics will think all is well whilst the engine will know differently.
