Going back to dealer, for P0121 code.....

[flyin99]

A while back, you may remember me having issues with truck just stopping at idle........no throttle response.....etc.........code P0121..........had new throttle body installed and now, after only 1 day, she's doing it again.............got me at a stop light while ago..........foot off the throttle and on the brake.....felt a little miss, then there goes the tach....just sweeping from almost dying to 5 or 600 RPM or so....almost no throttle response.......had to almost floor it to get the truck to move and she's bucking the whole way....wanting to die, but I stayed in it, so I could get home....it's -4 now.....too cold to be sitting out.....got it home....scanned it again........P0121 and P0506.........appt made for dealer next week........makes me sad....only 2,600 miles on it......
