Issues starting the car. Any advice?

[AutoItKing]

Revving up to about 2500 for a few seconds is normal for many modern four cylinders and some V6's. I haven't seen a new V8 do it though... But anyways, it's to warm up the engine quicker and get the oil moving than just idling. As we all know engines are more efficient once warmed up.
The RPMs will drop after a few seconds and it'll take another few minutes for it to get to it's normal idle of around 600RPM.

As for it slowly revving up to 3000, that's odd. I remember when I had my HFC it would try to idle at 600 for a little (really freakin loud too) and finally it'd rev up to 2000. Something to do with the extra flow or something...

I understand the car jumps up when it starts usually to about 2500 then slowly drops off. Think about turning your car on and it going up for double or triple the time it normally would and higher then it would and then start going down. Its not jumping to 3000 then coming down slowly.

since nobody seems to have the exact same thing happen im going to assume its not common and take it to the dealer this week.

Every once and awhile when i start the car the car slowly revs up to about 3000 rpm and the drops back down and when i mean slowly its like a 10 second process. It happened a few times maybe 3 weeks ago and then stopped until just this week when it happened twice more.

Today i drove it in the am. let it sit for about 40 hours and then went to start it and it turned over a few times instead of starting up right away.

Has anybody has similar issues.

...there is an ECM cold start update for the forte,have you had it done at your dealership? i do a few of these updates on a weekly basis.
