No seriously... It seems the minute my '99 TL hit 150K miles, everything started going wrong, which is fine except now I've got an issue that I can't figure out.

When the car is good and warm after several minutes of driving I'm hearing a sound from beneath the hood when I'm sitting at a light that sounds like someone plucking a rubber band or loose guitar string. I can't seem to recreate the noise when the car is in Park in the garage, but I hear it routinely today when the car is in gear and my foot is on the brake at a light. It also may occur when the A/C blowers kick on. Can't tell if its related as those fans turn on and off quite frequently when the A/C is engaged. The belt doesn't seem to have extra play in it that might cause the sound either.

Any ideas? I've searched the forum pretty hard and not found anyone with a similar problem... at least how I'm describing it.

Have I stumped the panel?

I guess it's possible it could just be the sound of my already fragile psyche, but it's a pretty loud "BOINGGGG" sound that I only hear when in the car. Better take us both in for an eval, I guess. Thanks anyhow, everyone.

when you first made this thread, i thought really hard on what could make a rubber band sound...
so far, I have nothing...

in for updates on what you find

I appreciate the effort justnspace... It's a difficult sound to describe. It's more "cartoonish" than a rubber band. It's more like the sound of one of those brass, coil-springed door backstops that mount on the baseboard in your home. If you've ever tripped on one of those, that's the sound, but a little muffled because it seems to originate from the engine compartment. I don't know... Stay tuned.

Hopefully the doc says your head is okay.

very interested in the outcome.

Forgot to update this thread with the final diagnostic from my Master Tech: The ABS seemed to be engaging at low stopping speed and making a "boing" like noise through the pedal. Faulty ABS sensor was identified and replaced. No more noises... in my head or otherwise.

Boing.....Boinging ! Glad to hear all is well !
