I have a stock (i hope it is) 98 Z28. When the car idles down from ignition. I am running around 900 RPMs. Is this right, or is my idle to high???

 

A4 or M6?

 

If its a 6 speed manual thats about right, if it is an automatic it should be around 550.

 

800-900 rpm is normal

 

So with my A4 sitting at 700 is that cool?

with the autos, i think it is different when in park and when in drive.

700 in park or neutral sounds about right

550 in drive as well

 

My stock A4 idle RPM's on Predator were:

P/N 645-676
D/OD 525-585

 

My 98 M6 car idled at 800.
My 01 A4 idles at 650 in park.

 

Thought I was the only one that wondered about that.....

Always seemed like mine (A4) ran a little low in gear at a light after it warmed up (about 600). Must admit it induced a slight chubby having the car shake at idle- I thought it was just screaming for a hotter cam to really make it thump!

I've always noticed the six speeds idle higher when coasting out of gear.

 

I believe mine at idle in drive were around 500, in park around 6 or 700.

 

I have an '02 six speed. I idle at 900 too.

 

you're kidding, i only idled that high on cold starts.

 

My car is usually idling at about 900. Used to be at exactly 1k, but with my new transmission, it went to 900. Seems to stay there whether in park or drive.
