  1. Usually with high NOx, there is a problem with the EGR, or catalytic converter, or high combustion temperature (overheating, running lean, vacuum leak).

     

    A high CO reading is a restriction of air mixing with the fuel, check air filter, and sensors dealing with air fuel,  MAP OR MAF, o2, ECT, TPS.

     

    Those numbers are pretty high, it would take more than just dumping 10oz of acetone in the tank to pass.

  2. I don't think it will matter which location you go to. What does matter is the attitude of the person doing the testing. I remember reading a thread on AWDPirates about someone failing twice with his WRX or STI, because of the person doing the testing.

     

    I don't think most of them will know the defferance between a 2.2 and a 2.5. They just plug in the OBDll, run it on the rollers with the sniffer up the pipe. I've passed several times with the check engine light on.

  3. Can I can just unbolt the sensors behind the knuckle to check them. 

     

     

    One of your wheel sensors is bad or has dirt/metal flakes stuck to the end, or one of the tone rings is full of crud. Tone ring and sensor are behind the brake rotors. The sensor has 1 bolt securing it to the knuckle.

    When you check the sensors, each one should have a small pin on the very end of the sensor. If the pin has corroded away the sensor has to be replaced.

  4. Woolite or the generic works great for cleaning interiors. For tougher stains, Folex, or Crud Cutter works great. Both can be found at Wal Mart, Home Depot, Lowes, etc.

    Yesterday I was cleaning the interior of my 92 Legacy wagon and found gear oil spilled on the rear seat and the carpet in the cargo area. I took the seats and carpet out and put them in the back of my Outback and went to the car wash down the street. They look fantastic now.
