朋友的车，九一年camry。测试数据如下：
ASM2525 test || Curb Idle Test
limit reading result || limit reading result
HC ppm 66 73 fail || 200 53 pass
CO% 0.37 0.19 pass || 1.00 0.07 pass
NO ppm 757 185 pass || N/A N/A N/A
RPM 1643 valid || RPM 726 vaild
Dilution 14.4 valid || Dilution 14.1 vaild

只是HC ppm超了一点，请大家给分析分析，是什么毛病？
谢谢！
