      right now our ait sensor is just siting there in the intake tube, it sometimes falls out and what not .
      i have noticed that the car seems very slugish in low RPMS in first gear. will the resistor mod help this any?

      i thought the resistor mod dident do anything and was just a scam
      here you go this should get u started:

      But I like the preset fuel map!

      Seriously, though... limp mode on on this car is more like awesome mode.

      Yeah, I am planning on replacing it, I'm just lazy
      Horsepower is how fast you hit the wall. Torque is how far the wall moves after you hit it.

      please explain, as i do not know much about how the different sensors work.

      First o2 sensor (in the exhaust manifold) is used by the ECU to determine how much fuel to use... so if there's a lot of o2 left in the exhaust, it knows it's running lean... if there's none, it's running rich... adjusts the amount of fuel being injected accordingly.

      Second o2 sensor (after the cat) lets the computer know if the catalytic converter is working properly.

      If the first one fails it falls back on a preset injection map, rather than "intelligently" injecting fuel.

      If the second one fails, I believe it does the same thing.

      Yup just to be safe. That's why engines are a lot less efficient when one of the o2 sensors is out.

      I went to Quartermaster Corps MOS/AIT Training in Va. Its a beautiful place.

      Unfortunately this training informed us to replace any/all sensors (etc, etc, etc) if broken. (I guess its what you expect to hear when your job is spending Tax-payer's money on auto parts and MREs, but really its not a bad gig...)

      It'd probably be better to just get the new one.....Is there any way to program an O2 sensor or the car's computer? If you could, maybe you could program the computer to try and take in more air and less fuel?

      Sorry I'm not much help, but I hope you are able to trick and sensor and pass emissions! YAY!
