Usually the tach is at 8 at idle but at times it drops to 6 or between 6 and 8.
My Cobalt was always at 8 (when warmed up) and never varied.
Is this normal for a Mazda 3?

Yes, I meant 600. Not worried, just curious

My Miata in the morning starts by idling at about 2000.... :tongue_smilie 1:

But then it drops.

My MS3 is more consistent, I don't even pay attention to it since it's under 1000 rpm when idling always and above 500.

Yeah, I dig that rocket ship at start up. It's actually kind of nice having the car tell me when it's OK to take off.

I do notice hesitation when the engine is cold, I have to take a u-turn when I go to lunch from work and the car doesn't want to move for a little while unless i gun it which I don't want to do since the engine isn't warmed up. I now make sure nobody is coming anywhere near me from the other direction when I make my u-turn.

Tach normally at 750.
If I drive on the freeway or drive ober 55 on the street, when I come to a stop at a red light the tach drops to a little above 500, sometimes it seems like it will stall but doesn't.
I've never had a car that varies at all. The Cobalt was at 800 every single time.

My 2011 2.5 is steady at 750 when warm and has been for almost 3 years and 36+k miles.
That sounds like where it should be all the time. I'll have to find out why it drops to 500. Just don't feel like going to the dealer until my first oil change in march.
