possible vac leak, pcv. possible iac valve too. a tcc or torque converter control solenoid can do this too. google its location and unplug it. if the problem fixes then it is the solenoid. you can drive it unplugged but will sacrifice some fuel mileage.

Recently changed fuel pump, fuel filter, did diagnostic tests. Said mass air flow sensor was out. Bought new one. And other sensor beside it. Idles good, when put in gear, spits and sputters, then dies. On the road. Only goes about 40, no faster
