Stalls in gear it gets under load the RPMs drop car bogs drops the needle down, it tries to catch itself then ultimately shuts off. The car has a small camshaft long tubes only did this a few times when I got it in December. It makes no sense; replaced idle control valve turned up the idle helped a little bit, still shuts off sometimes. I don’t know what else to look for next move MAP sensor if that doesn't solve it I will end up selling the car. I rebuild the engine still has issues.

When you put the car in gear does it stall quickly? like a stick shift car when you let the clutch out too fast? You could have a torque converter that has fallen apart inside and is locked up. Can you shoot a quick video to show me what is happening? That way I can tell for sure what the problem is, you can upload it in your response. This guide can help out as well:
