2012 v6 problems just purchased

Hey everybody I just picked up a 2012 v6 6 speed manual car, I got it from the original owner. It was sitting for alittle bit, everytbing was fine the 2 times I scanned the car before buying it, now a few days later it threw the check engine light po430 code bank 2 I’m assuming for an o2 sensor, car has alittle mis but I was gonna give it a tune up and throw plugs at it, but o2 sensor could make sense for the miss, now today the radio volume drops low and cuts out, it has a Navos system installed, now I’m wondering if the computer on this car is toast, or effected from sitting or are both these things just a coincidence, any body who may be able to share some knowledge ? Thanks. Who knows maybe other things will pop up soon

is "Navos" an aftermarket radio? if yes, I'd suspect that for the volume issue

O2 sensors can go bad, but I'd suspect the wiring or something else first

not sure if your year has the fuel filter in the line under the car, if it does, that is an easy thing to replace and might be due . . . other than that and cleaning the throttle body, air filter if aftermarket washable, and MAF sensor, there isn't much you can do by way of a "tune up"

does the car have any aftermarket parts, such as "cold air intake" and does it have a custom tune?
How old is the battery? A marginal battery on Mustangs can play havoc on the electronics.

The guy I bought it off said the battery is maybe a year old, the car was sitting though for maybe two months with no start, it started up right away the first time I looked at car, it was rough like it was gonna stall but it ran better once it ran for alittle so battery was definitely getting weak, I’m thinking it might not hurt to check all the grounds and clean them considering it sat

I’m not sure about the fuel filter location yet, but the car has stock air filter and no custom tune, thinking of checking all my grounds and cleaning them since the car did sit for abit
Does your car idle smooth? When in Park or in Drive with your foot on the brake?
