stalling

I have a 1993 chevy silverado 5.7l. I had gotten codes for the trany of the tcc and 1-2 2-3 solinoids and the problem was a stall when stopping or turning a corner. Intermittant problem not always. But i replaced tcc 1-2 2-3 solinoids and replaced the torque converter it was bad also. I still have the intermittant problem of stalling when stopping or turning a corner. The truck does have a new fuel pump and relay on. Any help anyone please?

I had the stalling when stopping and when I would hit the gas and then let off quickly. My mechanic replaced the low idle speed sensor. It made stop stalling but it still seems like it will stall for a second and then it starts runing smooth again. he told me that I would have to bring it back becuase there were other senors that are on the throttle body that could also be marginal to bad. you can test them with a volt meter I and a manual I think.
