I had to go in twice.

The first time I passed (technically), but just barely.

The second time I failed horribly.


First test:
-------------HC ppm------------------------CO%--------------
-----limit---reading---result----limit----reading-----result
idle__750_____78____PASS____1.00____0.92_____PASS

Second test:

idle__750____295____PASS____1.00____2.21_____FAIL
The 02 reading dropped dramatically during the second run, and now that I look, the rpm idle for test one was 908, test 2 was 608.

I'm sure the drop in RPMs made a difference...

There was one other factor. For test one I had the cone filter installed. That's why I got failed even though the emissions were fine. Second test I had the stock filter on.

Suggestions?
What is the proper idle? I thought it was around 690.
