Hey
I have an intermittent issue with my mustang from new 5 years ago. It runs between ok to super smooth and powerful.
when it’s rough it feels like it’s lacking torque and a bit lumpy in slow traffic to suddenly running as smooth as silk.
I’ve noticed that if I do a DTC reset the car runs great until the O2 sensor, Catalyst and O2 sensor heater rediness is complete then starts to go rough again.
could this be an O2 sensor issue ?. They seem to be reporting ok in FORScan.
