my 2001 explorer will not pass the emissions test i have tken the vehicle to two different mechanics , one thinks that the oxygen sensors are bad the other says that the catalyic converter or parts of the catalyic converter need to be replaced . recently i had the egr valve and sensor replaced .at the emmissions testing i was rejected because the catalyic converter said "not ready" . HELP
