When i start my car in the mornings the idle will rise to 1600-1700 and start making a weird buzzing noise. A normal startup idle i think is at 1500 and at that point it sounds normal. Can anyone shed some light as to why my car does this? tia.

 

the buzzing noise might be the abs pressurizing...

 

I dont have abs.

 

I don't have abs either, I don't have the buzz though. Is it normal to cold idle at 2000 rpm? My car does for about 5 minutes then goes down.

 

Your sig says you have a turbo, correct?? I'd assume that it is some turbo component. You might want to check some stuff. I haven't really dealt with turbos, so I don't have anything specific to suggest. Good Luck.

 

Your idle should drop after 2~3 minutes to 750~800 rpm. But then again, I live in SoCal, so I have no idea what effect the weather would have on the idle.

Anyways, I was told that idle should drop after 2~3 min max to 750rpm or so from the dealership.

 

mine buzzes sometimes for a couple secs... but I don't think anything's wrong.. it runs fine.

 

mine buzz's too! Its my heat shields ( crack )! Might want to check for that! IF that helps! If not, then..............right now cant help you! Good Luck

 

An initial 1600-1700 cold idle should be normal. After a minute or two, it should begin dropping. The buzzing is probably just a component rubbing or something. Or maybe you might wanna look over your Drag inline fuel pump which is usually kinda loud.
