HELP! 99.5 Pstroke is running strange

[Sgt. Stroker]

It was in the mid 50s today so I went out started my truck and let it warm up while I got my daughter dressed. 15 mins later I load my daughter and self into truck and go down the road. Power is fine, throttle response is good, and then all of a sudden I go over some railroad tracks (not fast or hard) let off the go pedal and press it again and there is no power and service engine soon light comes on.

It starts up almost normal except for a awful noise that it makes as it idles...

there is NO white smoke and its almost like a heavy LOBE sound.

I want to say its a bad injector but I was wanting a few more opinions from here.

a diesel mech. has told me its a "dead miss" bad injector

Ya, that's the only thing I could think of that would cause that
