1998 Infiniti QX4 3.3L MIL Lamp on
Posted to Asian Driveability on 6/15/2012 16 Replies

Afternoo Techs,

Have this QX that keeps throwing these codes. Checked MAF and tried a known good one - no change, Fuel pressure is right on spec, so I tried to run the O2's rich by shooting carb cleaner into a vac line and the highest they would go was .6 V?...
