My car idles really low like 400 rpms and its not like the other people where it jumps down and then back up. My car after it warms up idles at that it doesnt normally dip or anything it just idles really low. I wanna know if its just the timing and if is how can i fix this myself. Or whatelse can it be. By the way its a ITR motor. I searched but didnt come up with any real answer because everyone else has a dipping problem i dont.

 

Idle adjustment screw on the TB
