Yup, certainly seems like my Jetronic system is functioning properly... And from all my reading it appears that all my emission figures are very good EXCEPT for NOx. Latest emissions results (CO has gotten very low):
MPH=15 RPM=1520 %CO2=15.0 %O2=0.1 HC(PPM)=53 CO(%)=
.03 NOx(PPM) =
1508 FAIL
MPH=25 RPM=1793 %CO2=15.1 %O2=0.0 HC(PPM)=44 CO(%)=
.06 NOx(PPM)=
1156 FAIL
So, if I am now faced with replacing the Catalytic Converter system, does this mean replacing:
- just the rear Cat with another 3-way system?
- just the rear Cat with any aftermarket Cat? (which I've already done
)
- just the two front pre-Cats?
- all three Cats with an OEM replacements?
- or some other solution?
