Hi guys,
A couple months ago I started hearing a slight whistle under the hood when i hit the throttle. It goes away when the throttle is held at a steady pace. Today I decided to try to track it down and read quite a few posts on the forums but none of the other whistling threads seem to be like mine. I used a water mister around all my vacuum lines and didn't find any leaks. It seems mine is coming from the crescent moon shaped portion at the bottom of the throttle body face, just under the main air intake circle. I have tried carb cleaner but am not having any luck, any suggestions or has anyone had this issue before? Also, when i shut the jeeps engine down it sounds like air is being pushed back out of the throttle body making a pretty noticeable whoosh sound, is that normal?
Thanks,
Blake
