I hope the truck does not cost more than a few hundred dollars.

Try to get the OBD2 trouble codes read. That truck probably has set a bunch of them. Post the codes back here and we will try to help.

Did you ever figure out what it was . I just bought a 09 ford f150 and its doing just that ... and if i try to push it over the speed it chugs and makes loud noises ...feeling very ripped off at this point !!

The timing chains and cam phasers are notorious on the two and three valve titan motors, if its hi-mile and has multiple misfire codes check your chains,tensioners guide rails,VCT solenoids, and phasers. If guides are broken or chains are slack, get RID of it! I'm doing a timing set on my customer's E-350 superduty with 5.4 motor, it is going to cost him in excess of $2,400....Assuming there's no further damage. Remember people: These are interference engines!!!
