TEST 3 (FAILED BADLY)

MPH=15 RPM=1537 %CO2=14.6 %O2=0.4 HC(PPM)=143 CO(%)=.32 NOx(PPM) =1749 FAIL
MPH=25 RPM=1536 %CO2=15.0 %O2=0.1 HC(PPM)=46 CO(%)=.13 NOx(PPM)=706 Pass

The car was running at approximately 90C during the test - I added coolant to the system, as it was low during the previous day's test. Any idea why my numbers are going south?

In general, the used to run at approx 80C, but then I sprung a leak in the cooling system and now it usually runs at 100-105C.
