Re: Backpressure sensor?
I checked all four of my O2 sensors with my scanner and one of them was a bit sluggish on the readings, so I went ahead and replaced it. Now all four function properly, but I still see no difference. That's why I'm wondering if it might have a backpressure sensor. If it does, it could be telling the computer that there is little backpressure and the computer may be reacting by sending more fuel to the mixture.
Thanks for the help.
