Picked up this truck in April this year. Clean one owner fax report. The transmission was serviced, manifold intake and valve cover gaskets replaced by Dodge dealer. Fuel injectors cleaned. No trouble codes. Overall, shifts very good. Twice now, I was sitting at traffic light and it wanted to stall. Took out of gear and when placed back in gear, heard noises underneath maybe grinding, whirring. Moved, but not very good. When accelerated, heard a popping sound like it was mis firing, no acceleration. Pulled over, let idle and drove away fine. Is this sign of torque converter? Maybe idle is too low it was below 1000? I will take to Napa or the dealer to see if it had any trouble codes. I know that when I bought in April, dealer said it was clean of codes.

If it is the torque converter it may or may not put a code out. Try cleaning throttle plate on both sides and iac hole with choke cleaner they get gummy and cause stalling at lights. The whirring noise can be a belt or tensioner which recommended replacement is 60,000 miles for both.

Where/what is the belt or tensioner? In the torque converter or elsewhere? Thanks for the prompt reply.
