Hello, My husband ran a scan, & changed out both O2 sensors & MAFS, the check engine light is still going on. What is the problem. I am so ready to sell this car, I got it used from my mom after she passed away, & I only have 3,700 miles on the car. Please help.

Why you husband changed those parts? What were the codes when he ran the scan?
