Greetings,
Same thing happening to my VIOS. Any idea where to have throttle body cleaned and IACV adjusted? Except casa?
Thanks!

this is the same problem as my vios 1.5g 2006 that i'm trying to solve.
no CEL...finished cleaning TB, idle is fluctuating but may sites said it's normal due to ecu re-learning

TB cleaning is easy DIY style. still observing. also cleaned the MAF using a contact cleaner and cotton buds (it's just a thermistor, located after the air filter)

will check ISCV and PCV later...might re-check hoses and gaskets for vacuum leaks too

na testing mo na bang adjust ang minor? kung ok na ang minor. check the ohms resistan and the voltage of your Throttle Position Sensor

I don't know kung makakatulong pero I have this problem for over a year on a much older car and nung saturday lang naayos. A few questions:

1. Kelan nag low idle? Every time po ba nag eengage compressor aircon bigla mag dip yung rpm mo? or everytime na idle ka talagang mababa regardless kung naka on or off aircon mo?
2. If nag low yung RPM mo need mo ba tapakan yun gas para tumaas ulit?

This is what i learned so far:
1. If madumi throttle body mo magkakaissue ka sa Idle.
2. Pag sira Idle up sensor pag nag engage si aircon baba talaga yung rpm at ayaw umangat.
3. Pag mali yung sequence ng idle up at aircon mo kakainin ng compressor yung kuryente at baba din idle mo tapos erratic pa RPM mo so aakalain mo sira idle up sensor kase may delay yung pagtaas ng idle. The correct sequence kase is before the aircon compressor engages si idle up mo patataasin na nya yung idle mo para nag engage na nde magplunge yung RPM mo. Eto yung naging issue sa akin (kulang na lang servo palitan ko yun pala may issue lang sa wiring ng aircon ko).

if none of the above ka at gusto mo lang adjust yung idle mo as far as i know yung sensor sa servo ang i aadjust tapos pag naka on yung aircon dun naman sa idle up sensor.

baka nagalaw nyo yung TPS nyo sir noong mag linis kayo ng TB,..baka mali na reading ng ECU nyo? try to reset unplug the terminal battery for 15 sec.
