1998 TAHOE HOW TO TEST A CATALYTIC CONVERTER


If converter is cloged engine will have hard time getting rid of hot exhaust gasses and will have no power if it runs at all. Check for the gas that comes out - when you nail the engine lots of gas should come out - if it does not amount to much it is obstructing the flow of gasses and needs to be replaced.

My car says 'anti pollution fault' when I start it


If you drive your car more likely for short distances then engine will not get hot enough to start the regenerating process to clean the cloged particulate filter resulting in a antipollution fault.

Drive your car to a motorway or empty dual carriage way (best in nights). The temperature meter should be showing above 60°C when you begin with this process. Place 3rd gear and drive your car at 3000-3500 rev /min for 15 to 20 minutes to let the ecu to kick the regeneration process. Keep driving car for 15 minutes in this state will be enough to clean your catalytic converter and your problem will be solved. But if it doesn't then the problem is with your catalytic converter and more probabily you need to change it.
