94 Land Crusier stalls

I bought a 1994 Land Cruiser three weeks ago. I had the oil changed a few days ago (to Amsoil) and the next day the truck stalled two times from a cold start - once at stop light and the other while pulling into a parking lot. The following day it stalled another three times. It seems like after a five mile warm up the stalling goes away.



Yesterday afternoon I noticed that I can recreate the stalling when the truck is in motion (idling) and I’m turning left (not right - tested that.) If I sit idle and crank the wheel either direction the engine runs fine.



Any thoughts on what might be going on?
