OK…need help trouble shooting.

93 buick riviera 136k

When i go to give the car gas while the car is cold the car wants to die.
If i give it a lot of gas it will accelerate through it.
If i put it into gear it stalls.
once its completely warm it goes away intermitently
If i unplug the MAS it runs the same.
Ive already changed plug/wires and tested the coolant temp sensor and the TPS
I think its the MAS
What do you think? maybe knock sensor? i unplugged that and it ran the same.
Bad gas? dirty injectors?

Stick to MAFs … MAF boy.
