Old Mech -
Thanks. Since that 2007 test my NOx has gotten a lot worse. I barely past my last tset:
2007
2009
I am sure I will be out of compliance on my 2011 smog test (two different smog test facilities chose different gears for the test) :
I have since done an ignition-wire refresh, a new EGR, and new spark plugs. I have been planning to do an unofficial smog test to see where I am, but I have been too lazy.
But the original purpose of this thread was to be able to track my NOx for the purpose of making sure any non-OEM engine mods I do will not hurt my emissions. For instance, I had an EFIE, and I wanted to see what it was doing to my emissions. The EFIE has long since been disabled because I can't prove to myself that my emissions are good or bad.
