TB issue!

Bro could it be other problems? Cuz u rmb I changed the brown color sensor for the tb the idle becomes normal again buy awhile later the idle change to be like this again.. Is it okay to close the opening of air flow into the tb? It's been awhile... Thanks.
brown color sensor??... u mean the stepper motor??... that device is to control ur idling revs when aircond is switched on... meanwhile the airflow screw which u closed (i presume) is to control idling revs when aircond is switched off....
do a check... whats ur idling revs when aircond is switch on and off.... if u are getting irregular idling revs when aircond is switched on, its the stepper motor problem...
*presuming no other leaks besides ur throttle body problem*

sometimes simple things only will make ur tb problem and might not be related to ur stepper.
have u check ur throttle linkage? izzit loose?
have u check the throttle/butterfly position nut? (no.8 spanar to open and not the top idling nut)
it can be ur butterfly cant close effectively.
and tb's need periodic cleaning, meaning take it out, wash and polish.
