Just returned from the dealership. Explained my issue, told the service rep I cleaned the TB and now it has a high idle, he writes it up as "IDLE RELEARN" and 10 mins later my truck purrs like a kitten and my wallet is $95.00 lighter. They explained that the idle relearn is proprietary and can only be reset by their CONSULT machine. Now it doesn't not rev high when I start it, it idles at 625-650rpms, it does not surge and it does not downshift hard. Word to the wise fellow Nissan owners, either plan on taking it to the dealer for the service or plan to pay the piper for the relearn!
