1990 Mitsubishi Montero LS 3.0L Excessive Emissions
Posted to Asian Driveability on 1/27/2005 12 Replies

I am measuring about 900 ppm of nox gas in front of catalytic converter and 700 ppm after it. I dont feel this converter is doing its job. The ignition timing is to spec. and the vehicle runs fine. Oxygen sensor is switching fine and no vacuum leaks were found...
