One problem related to emission control has been reported for the 1999 Nissan Quest. The most recently reported issues are listed below.
This is the fourth time in 3 years that the same warning light has come on and at least the second time I've been told I have "spider webs in my cannister". ( I drive my car daily---don't see that happening). The computer codes, this time around, are: p1446 and p0325. Diagnosis: "needs vent control valve and cannister" " found spider webs in cannister and might need new one in future. " I've no idea what any of this means, but the same warning light with an easy fix (they said they wiped out the webs) indicates that somethins is wrong with the system.
