I had problems like this several times. Unfortunately, there are
several things that could cause similar problems. It could be the MAP
sensor, O2 sensor, EGR valve, AIS as already stated. Last time I had one
of the solenoids of my EGR stuck open or something like that. I bought
one of those sensor testers and it helped. It could be a lot of things.
Good Luck.
