This engine does not have an EGR. I retarded the timing and I failed to mention the cat on the car is newly installed, at least it looks like it. The car FAILED AGAIN today and now the numbers went throught the roof. On NOx under 25/25 test it read 2865 (vs. 1831 last time) out of 1440 allowed; and on the 50/15 test it read 2783 (vs. 2085 last time) out of 1577 allowed. Also HC went up on 50/15 test barely passing by 1 point @ 202.
