    I know all the TBI's whine, but mine has gotten really really loud lately. Is there something I should look for? Or something I can do to make it quieter?

    Maybe there's a vacuum leak? My brother's Camaro TPI whines a little louder than usual. We found a small leak where the air coming from the air filters connects to the MAP sensor. Nothing to worry about.

    I was told that the gasket under the TBI needs replacing after so long because of the use. I had to replace mine at about 95K on my Van....

    I look at the gasket but my engine was replaced less than 20k ago. It does sound a lot like a vaccum leak but so far I haven't been able to find one. Ya'll have any hints on finding it?
