Had a dead knock sensor in our 96 GXE (VQ30DE) so I replaced it then reset the ECM. Just drove it 78 miles and tested...no DTCs but the following monitors had not completed: Catalyst Monitor; Evaporative System Monitor; Oxygen Sensor Monitor. I was under the assumption that all you had to do was drive it 60 miles for all the monitors to complete but, after talking to a somewhat helpful mechanic was told that the car had drive cycles that were things like...drive for so many miles at a certain speed, let it cool, and a few other things I can't remember. Apparently each car is different and I'm hoping someone here can point me to what they are so I can get them cleared so I can complete the state inspection. Thanks for any help. Thanks for any help.
