Hopefully by now, the idle has reset itself, as there is now a lot more vacuum being produced. Im not sure which model you have, but I had the sport, and it was fully loaded, which apparently has a lot of vacuum producing pumps etc-thats the word I got from the dealer!- which will on occassion create a low rpm condition because of all the pumps running at the same time. Mine would on occassion actually stall after coming off an off ramp when I depressed the clutch- so you had to be aware of this. It might happen once a year, or 3 times in a day! It actually didn't happen for the last year I owned the truck. Hope you enjoy your ride.
