i just got my gsr motor built.. (NA) and im on a stock itr ecu for break in. my question is when i turn my AC on, its suppose to idle up, mine idles down to like 450 rpms for maybe a minute then idles back up to 1100. what could cause that dip in the rpms for that time??

 

Is the A/C dashpot still attached to the throttle body? round thing that attaches the the throttle linkage.

 

dunno what that is?
