08 Vios 1.3E rough idling (300-400rpm)

[sm2by]

Our Vios 1.3E M/T has developed this issue, while in stopped traffic, the car in neutral with the aircon on the car's RPM would occasionally drop to 300-400 RPM almost stalling.....
I don't know why this is happening.
There are no check engine or other warning lights showing up.
The car is only 21 mos. old, Casa-maintained (recent 25k checkup), not an ondoy victim
I tried using V-power or Xtreme97 (at different gas stations) to lessen the rough idling but the issue still persists.

Pa check nyo na yan sa Casa sir

It's kind of early in the car's life for this... but check the idle air control valve and your vacuum lines. While the odometer readings are low, the rubber vacuum lines and IACV can be affected by heat in traffic.

using higher octane gasoline wont cure it. tama si sir jmpet626, have it check sa casa.

wait. siguro kayo po ba na ginagawa talaga ng tama ang PMS ng auto niyo sa casa?

be on doubt pa din.

Thank you for your inputs guyz... I'll check with my CASA & SA about the issue.
I will soon post a video, since I recently caught the problem on camera this morning at my office's parking garage...

it must've been a case of bad gasoline.

yes, experienced it lots of times. make sure malinis mabuti ang lahat dun sa throttle body and sensors..
i have an officemate na nagpalinis din ng TB, hindi nawala yung low and rough idling. sinabi ko magpalinis lang sa iba......
nung nalinis, ok na sya.

Ganyan din ang problema nung auto namin dati, sinabi sa akin na madumi lang daw yung servo nung Vios namin kaya low idling. So far after malinis yung servo, bumalik na sa normal idling at pati yung hatak nung engine umayos na din.

guess wala kang suking shops/trusted mechanic. sa casa na lang para peace of mind ka. mayron silang gadget ( forgot the name) hooked up under the steering wheel para i-diagnose the cause.
