Tested again and it failed but the O2 sensor dropped the HC readings to 415. They mentioned how all the readings were lower this time, and that the idle test kept failing, I started explaining how it's always passed when they ran it the treadmill vs the idle test. So they ran it again this time on the treadmill so it was under a load. Passed just fine, had a 158 HC reading for the low speed. I think it needs a new Cat and then it would pass the idle test.
