Need help, puzzled
My 89 bronco II 2.9l, is reaaly causing me a headache, About a 3 weeks ago, my check engine light came on, so I pulled my codes, to find out that it only read 11, 10, 41. Since I know that the 41 was the o2 sensor, I went out & bought a new one. it was fine for 2 days, & then the light came back on, so I re-read the codes to find out that the o2 sensor was at fault again, so I took it back & got a new one. Only to still have my codes show that the 02 sensor is still the fault. To help anybody diagnose my problem the check engine light only comes on when I've been driving for a while, but once the truck it turned off & back on no light. To make a longer story short, could there be something else wrong that's saying its my o2, ie; my egr value, (which I have no idea where to find that), my throttle body being plugged, or any other sendor, Any replies would be great, I want to get my fuel mileage back, last few times, I was only get 5.xx.
Thanks
