Dealership should be able to fix both problem. Kill 2 birds w/ 1 stone.
anyways, car is shaky because the RPM is low and if it hits below a certain rpm, car would just shut off. Not sure how to fix it. I'm guessing cleaning the throttle body, new air filter, ecu reset, etc etc.
But I would take it to the dealer.

PS. it seems that engine temp is a bit lower in my car than it should be... i think these problems could be somehow linked together????

are you sure your reset worked?
try disconnecting your battery for 24 hours and see it your revs go up then.
How long have our engine been running before you took that pic?
Normal operating temp is in the middle.
and by the way.........it says REV in the middle.........so REV that bitch.![Big Grin](https://g35driver.com/forums/images/smilies/biggrin.gif)

Looks like it has some breathing problems....
I would clean the throttle body, i''m pretty sure it has carbon build-up. I would recommend disconnect the battery before your disconnect any harness from anywhere. This might eliminate the need for a idle reset or any other reset procedure.
Second, buy some electronic(non-residue) cleaner from radio shack, clean the map sensor.
And last but not least...replace your air filter.
DIY for these are all available somewhere. G/L

I seriously doubt it has anything to do with your thermostat or the cooling system at all. My coupe reaches normal driving temp
within a few block this time of year....NBFD! My guess the low idle has more to do with dirty throttle body and it never hurts to
have a clean air filter.
Disconnect the negative side of the battery for a few hours and see if that makes a difference.

and then see if it is the temp that it should be opening up with.
