What about during partial throttle--normal driving? During deceleration?
Running rich at idle is not unusual; running lean during decel is normal.
Did you just install the a/f guage and you're saying this? Or have you had the gauge in for a while and there's a change?
it runs rich just about all the time. every now and again for a few minnutes it will run normal but then it goes back to rich. i have had the gauge in the car for a while and just recently this started happening. i also have a na timer in my car that reads the a/f ratio, so i have two gauges telling me the same thing. i'm going to try changing my o2 and see if that works.
If you can pull the o2 , see the tip covered in black carbon, you should replace it....MAF is usually the most likely culprit...Befor you spend, try to get some codes pulled......
What are other symptoms of a bad O2 sensor? Bad idle?
Mine is running rich, but I can only tell by smell. A/F and NOS gauges in the mail...
thanks
