I reciently had a cylinder mis-firing that appeared to only be a loose connection. That problem triggered a check engine light. I have been monitoring the code checker to see if the misfire reappeares and have noticed that I have 2 monitoring tests that have not run if I read the information properly as they keep flashing on the monitor.
I also have a yellow light indicating the non running of these monitors. I have cycled the car through several trips and after saving the data off the computer, I reset the computer. It has not illumintated the check engine lamp and there are no diagnostic toruble codes stored in the computer.
The tests are the catalist monitor and the EVAP system monitor. I just had the smog checked last week and it passed in all catigories.
Am I too worried about these test not performing or should I be looking for something that I need to do?
Could the smog check people done something in the course of their testing that would have created this problem?
