Whats up with this??
Alright, i just got done changing my spark plugs, rear diff fluid, oil, put my shift kit in, and changed the tranny fluid. Now here's my question, when i turn my key in the On position, the throttle body flapper like shakes a few times, stops, then does it really quick again, Do the hemis normally do this and i havent noticed? Or is something wrong here? any help would be appreciated!

It is normal if your truck is a drive by wire for the TB plate to move, the ecm is verifying operation and setting it to start. If you have a tuner you can monitor throttle position. It will fluctuate between 8-12-17 and settle at 17% for the start and once your truck warms up it should settle to about 12% idling.
