Ok, I think I know the answer, but here is the question. Does the TB make a clicking sound when the motor is at idle? I have the 3.5 Ecoboost engine that started to stumble in the rpm's when coming to a stop. I am guessing it's time for a new TB, just want to be sure before buying.

TIA

 

Have you checked for error codes?

 

Yes, no codes are showing. Sounds like the plastic gears are slipping.

 

My 2019 had a ridiculously loud tick at idle, ended up being the PCV valve…might be worth looking at
