I had been dealing with a rough idle and occasional stalling at red lights in my 2017 Fiesta ST with ~26,000 miles. Largely stock powertrain. The problem was exacerbated when I installed the vibra-technics RMM, which made my idle REALLY rough (I couldn't understand why it was advertised as low NVH). While I did not have a CEL illuminated on the dash, I decided to scan for any background codes. Sure enough, i had P1450 and P2282. I did some research and decided to install the Whoosh 2014-2015 EVAP conversion kit and Whoosh boost hose (required for this kit if you're running the stock airbox).
Installation was very easy, and transformed the car. The idle is so smooth that I had to look down at my tach at red lights to make sure the engine was still running. The car also seems to pull harder/more smoothly.
I highly recommend doing this conversion to anyone who struggles with a rough idle or any of the issues mentioned.
