These are the words I didn't have to explain what I thought about the problem with my 2007 Outback automatic, 4cylinder engine
The check engine light comes on and the cruise control quits. Computer reader says code 171, running lean. After it's reset, it does it again when I'm on the road. The interval had become short, and I'm worried about TO WHAT the sensor is responding. Recently replaced an O2 sensor, but a week later it happened again, just driving around town. It's hot, but that's no excuse, is it?
I'd sure like for this to be fixed, and hope you people have some ideas.
Why doesn't it correct the air/fuel mixture? Then maybe the sensor would stop complaining.
