if I am reading the tach correctly
my car idles at 1 notch over the first longer line, that seems like it read 600RPM
is that in spec?
it's automatic.

 

I would assume that idle should be at 800rpm...but you know what happens when you assume

 

Well I hope, that's what mine idles at.

 

OK thanks guys,
I don't notice any vibrations

 

Just checked TIS because I thought I was wrong...550-800 is considered normal

 

my car use to idle closer to the 800 mark before the whole carbon build up. Now it idles at exactly where you're talking about. I noticed the low idle when my car started sounding like it was going to die every once in awhile at stops.

 

The idle will change depending on the load on the engine and when the A/C is on. When there is no load (in drive) and the A/C is off you should see 550 to 600 rpm. When there is a load and/or the A/C is on you should see a couple hundred more.
