Your not going to inspection obviously, without
checking for OBD Codes & making sure all
Emission Monitors run, or you just waste your time
as usual, sitting in line to fail
TYPE: OBD PO452 to see your codes
Going to have to component test the Evap System
& find the problem & resolve
200 miles is more than enough. p0420 is a cat code meaning the cat in the exhaust is not doing its job. you need to make sure there are no exhaust leaks before the downstream (last one) o2 sensor. if you can get all but 1 monitor to set without the check eng light coming on, you will pass pa emmissions.
whats the question?
