checks done:
-Compression test :: a bit low (~175) but even across all cylinders
-code reads :: only code pulled is P0420 (clogged cats) and P0300

the truck starts up and idles fine and you can get it up to highway speeds but if you put it under any load like towing anything or if you step on the gas to much it begins to surge like if you were to pulse the gas. I'm not even sure where to start with this as I've not really done work with titans before. i have a few ideas that it might be the coil packs causing the rear 4 not to fire, not enough fuel making it to the block or maybe something with the computer causing it to stop it's self from working under load. any ways to test these ideas of any other suggestions would be greatly appreciated
