What do I need to do to pass my truck for emissions if my HC is 133 and my NO is 1033. Ive changed my EGR valve, my vacuum isnt leaking and my timing is only advanced by 5 degrees. Prior to repairs my HC was 133 and my NO was 1030. I have an after market cat converter that is legal in the state of California.
