Greetings.
A friend of mine is looking at an early 80s injected 400. So far everything looks OK, but we're trying to figure out whether or not the emissions are OK.
Here's the numbers:
Left side at idle
HC(ppm) 321
CO% 2.69
O2% 1.86
CO2% 11.9
A/F Ratio 14.5
Right side at idle
HC(ppm) 181
CO% 0.43
O2% 3.24
CO2% 12.5
A/F Ratio 16.8
The reports shows "close to the same at 2000 RPM"
What does this show about the engine? Why might the left side and right be so different at the HC and CO%. Most importantly, does anyone know if it will pass Texas emissions in the Metroplex?
Gracias
