Honestly, I am damn surprised that I am even in the ballpark of passing numbers, so I HOPE that getting to pass will not be too much of a pain. The car has a 2.1L M42 built by Metric Mechanic with all of the bells and whistles. I was thinking that I would see NOx go through the roof with the 11.5:1 compression, but it didn't. In fact, I was only failing HC and CO emissions.
I ran the car for about 1000 miles with the wrong injectors and was running RICH, like black smoke at WOT. So it is seeming highly likely that the cat that I installed in 2009 is pretty dead. The car was running a bit rich in 2010 as well due to me tuning my wide-band wrong lol. Hell, the O2 sensor might be clonked too thanks to that since I replaced it at the same time as the cat in 2009.
In 2009, I passed SMOG with flying colors. Probably because I had a new cat installed and then drove straight to the test station. In 2011, I passed on the first try too, but my HC and NOx numbers had definitely increased. This year, here are the numbers from the first run:
15 MPH:
CO2: 14.15%
O2: 0%
HC: 135ppm (124ppm limit) FAIL
CO: 0.64% (0.78% limit)
NO: 429ppm (815ppm limit)
25 MPH:
CO2: 13.89%
O2: 0%
HC: 131ppm (98ppm limit) FAIL
CO: 0.96% (0.66% limit) FAIL
NO: 311ppm (754ppm limit)
I have a new Bosch LSU 4.2 wide band O2 sensor on the way and am getting a new Magnaflow cat put in tomorrow afternoon. Actually, I think that I am going to postpone the cat install until the new O2 sensor comes since the car is running rich, and rich running = cat death. Since the engine is basically new, there aren't any concerns on my end about carbon build up or plugged injectors since those are new too. As of now, I am suspecting that maybe the O2 is the main culprit here since, according to the calculator in the link below, my AFR's are 14.36 and 14.22. The ECU should be in open-loop mode and using the O2 sensor to maintain 14.7ish, so the sensor may well be fucked.
Will keep folks updated. Any thoughts?
