So I've gotten a check engine light about a week after installing a 2 step kit on my 2017 mustang everything seems fine but one time it, the vehicle sounded kinda funny when I was open full throttle almost like a tinging noise idk and the engine loght started blinking from solid after about 30 seconds it turned back solod. But I've attached the codes below. I have access to live data on the vehicle but I don't really know how to read it yet but willing to do all the research If someone can point me in the right direction. It's a 2017 mustang 5.0 with about 43k miles on it. Not sure if i should just replace the 02 sensors. I want to get some high flow cats eventaully. But any suggestions or help or tips or advice is greatly appreciated!!
