Hey everyone I have thes codes on my 2018 grand caravan for both o2 sensor and a rich fule condition on bank 2 iv replace both o2 sensor and when that didn't make the check engine light go out and still get the same 3 codes I replace the map sensor. That worked on a different vehicle I have but not in this case and now its cuasing a ruff idle and the car hesitates when accelerating and the check engine light starts flashing chiming but only wen its cold as soon as I start driving for a few seconds not long at all the light gose back to stedy on and dosent hesitate anymore, but still has a rough idol.. im thinking bad injector one stuck open! Any ideas would help greatly. Thanks everyone!
