Tried two stations in different counties 4 days apart... Jeffco (Golden) and Denver (Sheridan). Both refused to do the IM240 (dynamometer) test due to the catalyst monitor status being "Not Ready". The cashier at the Sheridan location mumbled something about me being able to request a different test type through the State Emissions Technical CenterHave you been to an Air Care Facility and they are refusing to put it on the dynamometer?
From my 98 manual...

What stands out to me:
It can take up to 2 Failures in a row to turn on the
MIL. After the MIL is ON, it takes 3 Good Trips to
turn the MIL OFF. After the MIL is OFF, the PCM
will self-erase the DTC after 40 Warm-up cycles. A
Warm-up cycle is counted when the ECT (Engine
Coolant Temperature Sensor) has crossed 160°F and
has risen by at least 40°F since the engine has been
started.
Thanks for the info. I have no stored codes (that Torque can read anyway) and no MIL.
