how many o2 sensors do I need for a 2004 mach1?


  • You have two pre cat o2 sensors and two o2 sensors after the cat. The two pre cat o2 sensors are for your air and fuel mixture and the two after the cat are for telling the ECM that the cat's are working properly. If your car is running bad and you are going to change any o2 sensor i would change the two pre cat o2 sensors (closest to the exhaust manifold) with the NTK o2 sensors from American Muscle. NTK o2 sensor is a great product. Ibanezshaun Year: 2000 Model: V6

    I put these sensors in when I did the offroad xpipe on my v6 and long tube headers with an slp loudmouth setup...the sensors worked for 4 months but now they have both stopped reading, now I have to replace again.

    02 sensor codes

    I have an '03 GT with SLP long tubes and other mods. My tune has a built in 02 sensor delay, but I started getting an 02 sensor slow to respond code and then an 02 heater code. I checked some other things first then decided to replace the sensors. I could clear the DTC with my tuner but it kept coming on every third time I'd start the car. They were easy to install and it cleared the problem up. The check engine light hasn't came back on and the idle even sounds better. I hope it helps my gas mileage out too. It's too early to tell yet.

    Great Part

    The O2 sensors worked great and the gas mileage went up as soon as I put them back in, and got even better once the cpu adjusted to them. Install was no problem at all ,and once I cleared the thrown codes, they check engine light never came back on.

    Works perfect

    Small increase in fuel economy extra extra 10-20 kms a tank but a big increase in power car feels much better accelerating especially at high speeds no stumbles and I can chirp the tires cruising at 100 now
