clean your mass air flow for a start. just wet a tissue and rub the resistors on there. be careful though, they are fragile.

My mass it flow is not even plugged in to anything the air box I have doesn't have a connector
And would the mass air flow really cause the truck to stall out and not have any power to drive passed idle with my foot on the pedal to the floor

yeah. you will have all kinds of throttle issues without it. your truck needs to know how much air is coming in so it can match the proper amount of fuel and all that. but if its been like that the whole time maybe its not your sole issue.

hmmm fuel starvation? dying when you turn the wheel or depress the brake is because you are using your power steering pump, which strains the motor. it sounds like low icp or low fuel pressure. im assuming low fuel pressure because it doesn't have any codes for icp...
