High Idle at start up, etc.

[Jess800120]

My 2007 cx-7 revs at 2000 rpms at start up, in any weather, IF the engine is cold, until I put it into another gear. Is THAT normal? I'm concerned b/c if I let my foot off the brake too quick it lurches. Someone told me the TPS(?) might be "sticking" and to spray it with WD-40...............?

Also, when I turn the engine off it squeaks a couple times within the first 30 seconds the engine has stopped. Like something rotating maybe? It's not the fan running.

Help! These seem like silly things to pay a mechanic for...

Normal to rev to 2,000 or 2,200 on cold start up. I alway let the idle drop to ~ 1,000 rpm before puting in gear.

Thank you! That's great news! I am curious why some vehicles do that and not others... My last 2 have been 6 cylinder small suv's and I never had that happen. Is it the turbocharger?

Not the turbo but, the way Mazda programed the controll mudule

Mine does the same thing.(2K rev at idle) ....It is annoying, but not abnormal.
