whistle sound

[Curtis]

The whistle I hear is not at highway speeds.
I hear it first thing in the morning after I leave the driveway and drive up my street. By the time I get to the stop sign 12 houses away and make a left, I don't hear it any more. Definitely sounds tranny related to me as it sounds like its under the floor.

I had a whistle noise and suspected almost everything including the right side wheel bearings. Mine sounded like it was everywhere including the moon roof. After trying everything else the noise (while probably not any louder, but me becoming more aware) was found to be the gas cap. If I adjusted the cap just a little, it would either quit or get louder. I treated the rubber seal with Armoral and it stopped. Nothing for about 6 months now.

Did your "check gas cap" light come on? Mine has started coming on despite resetting it with a code reader. Comes on every 2 weeks or so. Do these things wear out or is this some other kind of fuel system issue?

ok guys im willing to BET $$$ that i have found the answer to this annoying Whistle.

i was getting ready to clean the TB on the EX.. took off the TB, when i noticed a small spacer behind the TB, it was about 1/4" thick, and is hidden from view untill u remove the Throttle Body. the spacer had all these little plastic veins i guess to stop turbulence from the HUGE EGR tube that is dead center of the intake Neck.

the spacer is a piece of junk, and im just waiting for one of the small plastic veins to get ingested by the motor.

No lights... just a whistle. I seemed to notice it worse just after filling and that's what led me there.
