I had an emissions test done on my 81 B21F at DEQ yesterday. I'm hoping some of you can help me analyze what the numbers mean.

HC PPM max 220: my car 68 @ idle, 27 @ 2500 rpms.

CO(%) max 1.00: my car 0 @ idle, .32 @ 2500 rpms.

CO + CO2(%) min 6.0: my car 12.2 @ odle, 15.5 @ 2500 rpms.

Does all this sound pretty good? My only driveability problem is a rough idle which I'm still trying to track down. Do you see any indicators here? I know I have a small intake air leak at either the #4 injector or the #4 intake runner which I'm working on today.

Thanks in advance for any help you can give.
