This fit my 97 Blazer perfectly and has been working great. Only took 15 minutes to remove and replace the old o2 sensor. Check engine light (MIL) turns off after several successful drive cycles with out the ECU detecting any problems or if you have a scan tool you can erase the DTC's set in the ECU and that will clear the check engine light (MIL) and if the o2 sensor was your true problem then the light should not come back on. If it comes back then you miss diagnosed the problem and you probably changed a good o2 sensor. Don't blame the sensor for poor a mechanical diagnoses. Check engine lights are only indicators to symptoms they don't tell you how to fix the car even with a OBD2 code reader. Do your research before you buy. The biggest problem on this site are people who buy the wrong item because they did not research then give the item a bad review because it did not fit. Read! read!! read!!! and then read!!!! some more before you order.

I bought a pair of these for my 2000 Olds Bravada. The old ones were pretty much seized on and I had to use some physics (cheater bar) to get them loose. I replaced the upstream sensors. Performance seemed a little more responsive, fuel mileage a slight increase, but not much. I replaced these because the old ones were throwing a code.

Oem part that fits and functions just as it was intended. No more check engine light, and my s10 idles much smoother now. I plan to replace the other 2 sensors on the truck as well. Fuel mileage did increase slightly, hopefully it will improve further with 2 more new sensors. Great price on an oem part too, much less expensive than the local auto parts stores.

I BOUGHT TWO OXYGEN SENSORS ON LINE AT A CHEAPER PRICE. I DROVE THE VEHICLE 800 MILES, CHECK ENGINE LIGHT CAME ON AND BOTH NEEDED TO BE REPLACED AGAIN. I THEN BOUGHT TWO AFS105 SENSORS AND I HAVE NOT HAD ANY PROBLEMS. IT IS ALWAYS BEST TO BUY REPLACEMENT PARTS THAT ARE MANUFACTURED BY THE VEHICLE MANUFACTURER.

I replaced the upstream sensors in my 1998 Chevy Blazer after the computer started throwing O2 codes, P0131 and then P0135 under hard acceleration. For the last several thousand miles, the engine had started running very rough, the idle would slowly creep upward if the truck was left alone, it was pinging and hard to start.

I knew the old sensors were definitely bad when I removed them because they were caked with a thick white dust. According to the service manual, this is a tell-tale of a dead O2. Well, I'm not complaining, the originals were in there for 200k miles.

After replacing these sensors, the engine starts quicker, runs very smooth, no more pinging, and the POWER. I used to push the accelerator to the floor on the hill in my neighborhood, at the top of the hill, I would be going 20MPH. Now, I only push the pedal 1/2 way down and I am going 50 a the top! This thing spins tires through first and all the way to the top of second gear now if I'm not careful. This is with a brand new set of Firestone Transforce A/T tires that are a size bigger than the original.

Only time will tell if they last as long as the originals, but one thing is for certain: installing these was like taking 10 years off the age of this truck.
