o2 Problem: Help needed
I replaced them less than a year ago and now I'm getting the SES code: P0131.
Apparently it has something to do with low voltage on my bank 1 sensor 1 o2 sensor...
The car is acting "puttery" when I come to a stop or am idling. What is the actual problem? I can't imagine I should have to replace the o2s so soon...
Any info would be appreciated. Thanks.
