whistle noise after startup

I have noticed a whistle noise after startup. It only lasts for a second and happensabout 20 sec. after I start my car. No a/c or anything on. Just letting it warm up like always. Is this normal? It sounded like it came from the front of the car. If it is normal what the hell is it? TIA

Air Pump, for the emissions system. Normal.

How funny, I've been wondering about that myself. What exactly does an 'air pump' do anyway? Neither of my old Honda's had them (90 ED3 Civic, and 88 Prelude).

None of your previous cars needed to pass strict LEV standards.

The pumps speed up the warm-up of the catalyzer.

So let's say you live in a non-emissions-tested zone and want to use a straight-pipe instead of the catalytic converter... would removing/bypassing the air pump system honestly make any difference?

I'm just curious... most of Utah has normal emissions standards.</TD></TR></TABLE>

you dont have to remove the air pump if you run with test pipe...

i dont think you know how air pump work... its not connected to catalytic converter what so evAr...

The pump works with the EGR valve and pumps through the intake. It does not connect to the catalyzer in any way. You can do both: remove the air pump and put on a test pipe.
