On my 07 GT,When the car is cold The rpms go to 2000 and slowly come down, I would say 1500 in10 seconds and 1000 in 45seconds. Does this happen to all?

 

I just cold started mine. I did 2000 RPM for about 1 second, then dropped immediately to 1500 RPM and in about 10 sec dropped again to 1,000 RPM.

 

is ur car tuned?Cold air intake?

 

Mine is completely stock, but Thurman's has CAI according to his sig...

 

Same here....CAI and tune (FRPP) If I remember right, it did it stock, too...

 

BTW, after about 2 min iddling mine dropped to about 600-700 RPMs.

 

cai and tuned.
P.S. tpony,600 seems very low

 

same thing happens to my v6 but only durin the winter

 

I'll keep an eye on it..

 

The colder it is outside the longer it will rev higher before dropping down to the correct idle. When it was below zero the past couple weeks around here it would rev at around 1500rpm for like 3-5 mins before dropping below 1000.
