Ok my car runs and idles like a new car when its at full temperature but not when its cold. After a cold start, when drive it around, the RPM dips noticably whenever I make a stop or steer. The car has been tuned up a while back. Any ideas?

my car does it every morning, when it warms up its fine. maybe its because the idle is higher when the car is cold, it goes down after shifts or if you let off the gas, then it bumps back up...

Yea. its annoying when u drive around a shopping center or ur complex and ur tach bounces everytime u stop or turn. I just remote start my car and let it warm up for 10 minutes before I drive off now.

How about the Idle Speed Control? Would this be the culprit?
