When the car is warmed up, I get to a stop sign and turn either left or right my cars really loses power. It bogs down. It doesn't bog down when I go straight. It is also more apparent when the outside temperature is warmer. Ive changed so many things, plugs, wires, sensors, cat converter. Many shops cant find the answer. Can you help?

I had the same problem with my 1994 Bonneville. Drove me crazy, and sometimes it would cut off while in a turn. I changed oxygen sensor and EGR. I had no more problems. I hope it works for you.
