I have a high picth hum when my engine is idle at 700-1000 rpm above and below that the engine sounds fine and everything feels fine. I can also feel some shaking in the steering wheel when i get between 700-1000 rpm. Could this be the timing belt? or a control arm? I have replaced the timing belt before but that was a while ago ( don't remember when but prob around 60000) and I am getting close to 120000 miles. This noise started showing up after I went into a dip too fast I believe and had a real hard thud.

 

You might have damaged something under your car when you went through the dip.

Jack it up, crawl under it and see if you find some damage.

 

I looked and thought I saw something out of place but I wasn't sure. I don't spend enough time under there to be sure can anyone give me a pic of the bottom of their vg engine area?

 

power steering pump?

my power steering pump wines at idle but only when its cold out

 

If its rpm related, quite possibly belts touching smtg like mud shields? THere are some pics - but maybe not what u want... http://www.cardomain.com/ride/748507/23

Take the shields off and jack up as suggested... Check that belts are tight; pwr steering bolt (4.) should be tight.

 

I know this will sound hilarious, but my mom got this problem on her old saab 900 after I made a burn out with it...

the car sounded real strange when engaging clutch, a kind of scraping sound, plus the car was shaking and had a real rough idle. and when disengaging it went back to just whining.

it turned out to be the flywheel bolts. 5 out of 7 of them had broke.

but I hardly belive this is what happened to you, it's more of a funny incident I just had to share

 

I think this was sad as u didnt get em all: two bolts were left standing...

 

yeah but they were kinda bent and in real bad shape
