Thank you so much for your help! I really appreciate it.

I checked out your website and was fascinated with all the FAQs! I,
too, have a buzz at certain RPMs (typically when I'm at a low speed in
2nd or 3rd) in the rear of my car. I wonder if I have the Honda
"A-pipe" rattle?

My friend said something about Honda offering a "buzz" kit to fix the
problem but I never looked into it because it didn't seem all that
problematic.

Thanks again!

Jessica

Don't know specifically, but most cars have restrictions on when the test is
to be attempted. Quantity of fuel between X and X; Temperature between X and
X and engine cold or the first start in the day. Often when dealing with the
evap system you may have a driver that never meets the requirements so the
test never gets performed.

I was wondering about that. Obviously the test would have to be performed
under certain conditions, and if those condtions were never met, the test
would never be performed. I guess another example would be the cat
efficiency test (P0420 error).
