OKAY... here are some test results:
Car miles 171138, toyota camry, V6
*Visual* inspection of ECS:
PCV, EGR, O2 sensor, Fuel Cap, EVAP, spark control, wiring to sensors, liquid fuel leak, malfunction indicator light, catalytic converter, fuel ignition, vacuum lines, fuel cap integrity: ALL PASS
ASM Emissions test:
15 mph rpm:1728 C02:13.7 O2: 0.9 HC:*160*(max 84) CO:0.15 NO 375
25mph rpm:1681 CO2:13.5 O2: 0.7 HC: 48 CO 0.03 NO: 79
So it seems the 15mph HC is the line that failed the test.
