rpm does not pass about 4.5~5 when car is at stop.
 

So.... I dont kno why but, my car doesnt go over 4~5 when im in stop, N or 1st gear with clutch pressed.

its pretty cold here temp about 15F.
is my car smart enough, saying doing let the clutch go at rpm 7 when its that cold? LOL

no problem when the car is in motion, i can hit the gas and goes all the way up to 7.

any help?

You should be able to rev it past 4-5k in 1st gear holding in the clutch.

But why should it if the car is at a stop?

From Owners Manual: When racing the engine up to 4,500 rpm or more under no load condition, the engine will enter the fuel cut mode


Putting it in gear deactivates it. :)

7AT's won't be able to do this though as we have no clutch to separate the motor from tranny. :(

Does this happen all the time or only when it is cold? Also, does it happen when your coolant temp is Cold or at normal operating temp?

I'm just wondering if there is a feature in our cars that prevent over-revving when the engine is cold? I know in the Mazda Rx8, there is a safety feature that makes sure you can't rev it high when the engine hasn't reached operating temperature.

Word of caution: You shouldn't be revving your engine and holding your revs (for a sustained period) close to the redline when it is cold or in N or when there is no load (clutch in).
