I noticed couple of days ago that in the morning right after the car warms up the idle is wierd. In neutral I rev it up a little and when it comes back down it goes to very low rpm the car starts to shake almost about to die and than goes to normall. It mostly happens in the moring and almost every time I rew it up. What do you guys think? Is it map sensor?

 

My MY04 has acted that way since it came off the lot brand new. I've scoured the forums and have been confident for some time now that it is simply the ECU making its regular adjustments.

That's the short version. If the car actually stalls out, then you have a problem, but not unitl.

 

And the best advice seems to be, let it recover on its own. Don't use the throttle to keep idle up when it dips.

 

Search. This has been discussed a lot. You may want to remove the IAC and clean it out. Could be clogged...

Also trying a MAP whack and resetting the ECU....
