    Curious about something

    ok. i was changing the oil in my 99 camaro this weekend. changed it, all done, and started back up, and let run for a few. when i heard this loud ass hissing noise. i started listening around the engine bay. and heard it was deffinatly a vacuum leak. tracked it down to a vacuum line on the intake, directly behind the throttle body on the passenger side. the whole like was rotted through. and was stretchy. well, i went up to autzoone and got a piece of hose for it, fixed it right there. but noticed. that this line that runs from the intake hooks into this huge vacuum line that appears to run into the car itself. for hvac? i dunno. but i noticed that this line has a grounding clamp and wire hooked up to it. im curious as to why gm would run a grounding wire to a vacuum line like this??? any ideas?

    i'm not quite sure what "hose" your talking about, but maybe sensor wires are in that hose. on my old G/a they looked like hoses going into the car but it was actually a tube like hose that held wires in it.

    i think i might. im not sure. but as i was putting the new hose on i could hear like a little ball earing floating around in it. and noticed it was a metal piece with a nipple on it for the hose to go on.. and im retty damn sure, that gm wouldnt run a vacuum line through a "hose" with wires through it. im just curious as to why this piece is grounded. it has rubber hose on one end, and plastic like wrapped hose on the other. maybe my car is just speshul. haha

    I guess it's possible for the pcv to create energy through friction or static...that mixed with any excess fumes wouldn't be a good thing.

    I just pulled that outta my ass though...I really have no idea
