truck is running really bad it hesitates when i hit gas like its bogging out it runs fine untill it warms up, if i hit gas full throttle the whole truck just vibrates, so pretty much it lost a lot of power
 
Try unplugging the MAF sensor at the air intake tube. If the problem clears up, the MAF is bad. This can cause these problems. 4 wire flat shaped plug.
