Big Red, I just became a member and haven't received any posting rights yet. I was hoping though (in the meantime) if you could point me in the right direction. I just bought an 09 1500 with the5.7L truck a couple of weeks and noticed this a few times now. I'll approach a signal and after coming to a complete stop - the engine will drop RPM's after a slight pause (3 seconds after dead stop), the lights will dim, the engine will nearly stall and then the RPM's pop back up and the lights are on at full-bright? Any thoughts? Is this a transmission issue? Thanks.
