You can't think it's not a fuel issue, you have to know it's not. It sounds like my truck with the front tank, the fuel pump is going out. It will idle and go with easy throttle but sudden throttle movement it dies.

 

ill look into it further but why would it be throwing all of these codes for airflow problems

 

I might have overlooked something, but those codes aren't airflow related. You'll get codes that aren't as simple as they seem - people throw parts at cars all the time and get frustrated when it doesn't help. Just because you get a code for a particular sensor, it doesn't mean the sensor is bad - it might be the sensor telling you that something else is wrong.

Just eliminate one potential cause at a time - if sean thinks it's the fuel pump or fuel pressure, check that first. With a fuel pressure guage. He knows his stuff, and has proven over and over that he's usually right on track. If you can prove to yourself that it isn't fuel related, we'll move on to the next probable cause and test it.

Be sure to jot down some notes and keep track of what you've done, what you found, and what might be next. Or use this thread for that purpose, so we can continue to help 'decode the codes' and help you find the solution.

 

alright ill check into it this weekend got alot going on right now but thanks for help and ill keep yall updated he could be right with the fuel though because the pump on this thing is loud as hell sounds like a chevrolet pump haha

 

That's a good sign one of your pumps are bad. When the in tank pump goes bad the pump on the frame is loud because there is no gas being pumped to it. You have a pump in each tank and one on the frame.
