2005 mercury monterey van
Hi Folks,
I have a 2005 mercury Monterey van with a check engine light on. Autozone diagnosed either a mass air flow sensor or O2 sensor problem. I tried cleaning the air flow sensor with air flow sensor cleaner but check engine light is still on. Any suggestions on which part is more likely to be at fault?
The van runs and drives great otherwise but need to pass emissions. Thanks in advance for any input.
