Got it for 'free' couple years ago from the BIL. Needed a new battery, brakes, and block back exhaust along with little odds and ends (lights, radio, etc.). All in I'm $750ish into it and couldn't be happier with how it runs.
Crazy thing about it is it has been a Chicago Jeep the entire time and the floorpans are just now starting to rot. I'll get another 3 years at least thanks to rust converter and flex seal [emoji1787]
As far as yours goes, swap in a new pressure sensor and see what that does.

Fiesta got to sit for one more day before my vacation is over and back to 60 miles daily on her.
