So I just failed a smog test with high nox and I've been doing all kinds of testing from the fsm. I tested the egr valve,modulator,vsv and all kinds of other acronyms.
Then I notice this.
What? How have I missed this over the last year and a half of working on this thing? How did I pass smog last year?
Would this even cause high nox?
