Emission Test - OBD NOT READY?
Hi there,
I went to emission test yesterday, they said that my car is not OBD ready.
I've derived the car about 85 miles after MAF, ICV cleaning and OBD reset now. The guy from emission test station was talking about "Drive Cycle Time" how should I know, when the car becomes OBD ready to go there again?
Vehicles with excessive unset readiness indictors will be rejected from testing. (Monitors indicate the OBD system’s readiness to be audited. Model Year (MY) 2000 and older may have no more than 2 monitors unset. MY 2001 and newer may have no more than 1 unset monitor.)

More on Emission Test - OBD NOT READY? Drive Cycle
I just had my emission test here in NJ. They plug into the OBD. I had cleared a code with my scan tool about 80 miles earlier, and when the Inspection Station dude hooked up he said my OBD was "Not Ready", and that I probably needed some more Drive Cycles. OK, anyone have an idea how long after a reset you have drive or how many times you have to start the car to "totally" clear everything so that the OBD is "Ready"?
I don't want to bring the car back to the Inspection Station too soon, if I need more "drive cycles". Help?
