Weird sound from revving engine while driving - VIOS

It could be your fuel. That could be your engine knocking.

Finish up your current tank of gas and then fill up with fuel from another gas station with Blaze, V-Power, XCS or any fuel that is hi-octane. Half a tank should suffice. Drive it for a few days and see if the problem goes away.

If it goes away, you may have filled up previously with contaminated or low-octane gas. If the problem persists, then it's probably something else.

Pa check mo rin kung tama engine timing ng sasakyan mo.

+ 1 kay pareng speed. Baka masyadong advance ang timing.

Hi sir speed! If it's not a bother to you, can you provide me with more details with this 'timing' ng vios? Bale kung ano dapat yung titignan at gagalawin sa vios (kung knowleadgeable ka lang naman po sa vios). Di kasi ako familiar sa mga ganyan.

Good day! I've been using XCS (from shell unleaded to XCS). May usap-usapan nga pong yung ibang station ng petron eh contaminated yung gasolina nila. How true is this and posible kayang victim ang car ko? I've been gassing kasi sa mga Petron sa Las Pinas (near Zapote, Verdan, and Bf resort).

It's a distinct possibility. It's been raining like crazy for several weeks now. May possibility na natyempuhan yung auto mo.

Kaya suggestion ko, sa ibang gas station ka muna magpa-karga, para lang ma-isolate kung bad gas lang ang problem.

Regarding sa timing, this is not for everybody. I suggest pa-tingin mo nalang sa casa or a reputable talyer. Pero, VVTI na yan, right? Baka di na talaga kailangan ng manual change ng timing. Usually, bahala ang ECM sa pagtimpla ng lahat ng parameters (A/F ratio and to some extent, timing among others).
