2017 Fiesta ST - 100% stock throwing CEL: P0420

[TurTakashi]

With the wife not working, the car has been sitting in the garage. Have not scheduled an appointment with the ford dealer yet but hopefully soon. I will definitely post the results in here after they confirm it is the cat or who knows what else.

Annnnd... OP died.

nah, but I do feel like a little of part of me dies every time I drive the fiST instead of the Evo 🤦‍♂️

I’ll post up the issue and solution when we finally bring it in to the dealer.

Did you ever replace the downstream O2 sensor? I thought that's what most were recommending to do before you went to the dealer. If you are home now you have plenty of time to do this before you hit up the dealer.

What do you like so much better about the Evo?

It's like a FiST on steroids! It gives you the same visceral driving experience but with a much larger envelope of performance. It's faster, brakes better, handles better and communicates with the driver even better than the FiST. At least the Evo VIII and IX did...not so much in the X.

That's interesting to hear. I've driven a number of current fun cars in search of the "right" option. I never tried an Evo, maybe I should have even just as a comparison point. The FiST isn't perfect, but I came to the conclusion that only the ND Miata is better, below say a Cayman.

The Cayman is also extremely good! I've wanted one since I tested it for Motor Trend Car of the Year. It's brilliant!

We actually replaced the first o2 sensor before the downpipe. Maybe we should have done the other?

While the fiST provides an amazing driving experience the Evo is a multiplier of that same type of fun. The feeling of driving what almost feels like a go kart on the street. The Evo is built much better. But here are my top reasons: Only has 5 gears. A nice simple leather interior with heated Recaros but has much more interior room. Brembos, sunroof, HIDs, Rockford Fosgate sound system - which are all stock features. it's easy to modify and picks up nice whp gains with minimal mods. It has been very reliable being the original owner and currently at 86K miles with no issues. Capable of varying terrain (has tarmac, gravel and snow mode) SuperAllWheelControl with ActiveYawControl/ 337whp/350tq (mustang dyno) is perfect for a daily IMO.
Out of the handfuls of cars we have owned, it is by far my favorite for a daily driver.
Also, the 4b11T has proven very stout. There are more and more 600whp stock block builds these days proving this.

Appointment (finally) scheduled for tomorrow morning with the local Ford dealer.
Will keep y'all posted.

Dealership confirmed the catalytic converter is bad. The vehicle is currently at 51k miles.
They have ordered a replacement under warranty
