Hello all, I've had my '89 Wag for a bit over a month. All of the Emissions controls except the PCV valve had been disabled or removed. With lots of help from this board I was able to get everything put back on. Well this week, I was able to PASS Texas emissions testing!!!! I'm pretty excited about that, but they had to run it twice to get it to pass. The HC was just over on the first run. They warmed it up, and it was able to pass. Here are the results:
High Speed (25mph)
Standard Current Result
HC(ppm) 155 113 PASS
CO(%) 1.91 0.14 PASS
CO2(%) 14.2
o2(%) 0.8
Nox(ppm) 990 490 PASS
DILUTION: >6.0 14.34 PASS
Low Speed (15mph)
Standard Current Result
HC(ppm) 159 144 PASS
CO(%) 1.42 0.26 PASS
CO2(%) 14.2
o2(%) 0.6
Nox(ppm) 1076 670 PASS
DILUTION: >6.0 14.46 PASS
They didn't tell me, but I suspect it was the low speed HC test that originally failed. What would cause that reading to be high? Do any of the other results tell me anything about the health of the engine? I'm very happy that I passed, but just curious what I may need to do to keep it passing in future years. The HC reading is the only one that seems to have a potential problem.
Thanks,
Scott
