5.9 magnum bogging?? fuel injectors maybe???
okay this one i can't really figure out....the truck is throwing no error codes, but if i'm stopped and i step on the gas to accelerate quickly, the truck doesn't accelerate nor does the rpm increase. rather the rpm decreases to like 300 rpm and then it takes a couple of seconds before the truck actually moves, before the motor actually gets its rpms up...anyone have any idea?

If its a sensor, my money would be on the TPS, but you've got a lot of choices here.
From cheapest/easiest fix to most expensive:
1. Remove Throttle Body and Clean with Brake Parts Cleaner or the like. Reinstall and retest.
2. Test Catalytic Converter with a temp gun, if it's hotter going in than coming out, the Cat's clogged and needs to be replaced.
3. Test Fuel Pump at Schrader Valve on fuel rail to make sure it's holding 46-49 PSI at all times and in all conditions.
4. Replace TPS, IAC, or both
5. Replace Crank Sensor. PITA to get to and about $80 if I remember correctly.
