Hi all , have a 2011 2.0 Mazda 3 auto with 160000km. Mostly highway use moderately agressive driving.
FWIW Haven't changed oil in too long but the volume of oil is good.
No previous issues save damaging ABS during a suspension swap a year ago TBH have never fixed it but, no performance issues that entire time. Alignment needed cants to the left slightly.
Swerved around a drive that dipped into my lane and rev out fast to avoid rear ending. Car threw a P2243 but no issue or performance change after driving home about 45 min highway time. Ran my neighbours OBD2 when home and had 2 codes. P2243, and P2243 P. Had done a few big revs and no issues so reset ECU and drove it around fine for a while.
Drove the whole next day to work without any perceived issues, my commute is about 2.5 hours roudntip in varied conditions so not a short haul.
Wife took it out next day and said it felt off... she then had a catastrophic flat in an intersection (unavoidable pot hole) and pulled over about 50ft ahead where safe. Tire half off rim. Told me burning smell present.
Louded up the jackstands and big jack in our scoob and threw the donut on. After turning car back on Code was back. p2243. Car shuddered for a while then settled.
Driving home (about 1km) and it felt like it was 500-750 too high on the rev range. Half way the CEL came on again. Got it parked and three codes. "P2243", N/A, P2243 P"
DIdn't smell like rotten eggs when swapping tired but vague scent from exhaust. May have been in my head.
What are thoughts, did i blow the CAT? or is it just a shotty 02. Should i just put winters on so the donut is off, order new 02 sensor both up and downstream, replace oil and reset ECU? Should this solve it at this point.
Money tight with kid and christmas so really not wanting big shop fees if i can do it myself. CAT cannot do myself.
