This morning i started my truck, started fine. Backed out of my driveway and went to step on the accelerator and the rpm's never moved when i was in drive. As soon as i stopped and put it into park my truck was shaking quite a bit. What would cause this problem if any one could help.

 

Could be anything. What have you checked yourself so far?

 

No OBD codes?

Anyway, it kinda sounds like it might have gone into the 'limp' mode. Happened to me when my battery was failing and the voltage dropped below some minimum.
