Whine Noise - High Frequency Vibration around Throttle Body
Hi Guys,
I have a 1999 Frontier pickup with the inline four engine. Non California. About 120K miles. It is suddenly making a med-high pitch whine sound - seems it is coming from around or under the throttle body. Pitch of whine changes with engine speed. I can feel the vibration when I touch the air cleaner housing. Also there is a small amount of smoke coming from this area. Any ideas? Thanks. -Will |
