On my 2002 Buick Rendezvous I have change 3 solenoids in the transmission and still having the same problem no guts no acceleration and drive have to start off in first gear stalls sometimes
Is the problem that you have no engine power? Cars always start out in first gear from a stop. Does it have good power once up to speed but no power off the line? If so maybe the car is not going into first gear but is starting out in second or third gear.
Unplug your EGR valve and see if it runs better. If no change, unplug your Mass Air Flow sensor and see if it will run better. One of the two may be bad or severely dirty.
