Garagal na tunog pag accelerate

[janry1]

I own a 2nd gen toyota vios 1.5g MT. Ask ko lang po other vios owners kung naexperience niyo ito. When applying sudden force in the accelerator, parang medyo garagal ang sound pagaccelerate (yung engine medyo nagtutunog truck) although this doesn't happen pag slight lang naman ang pagaccelerate. Minsan kasi pagnagovertake, kailangan medyo biglaan magaccelerate. Any insights?

By accelerating, how high does your tachometer go? IMHO most cars tend to sound coarse when reaching 4,000 to 5,000 rpm. BTW, at what gear do you usually overtake?

Garagal na tunog pag accelerate......
Siguro sir driving habit,sa akin wla naman ako na encounter na garagal if nag accelerate during overtaking or rev the engine during running....
Most likely pag gagaragal ang engine naka high shift gear & low rev engine. Example nka shift gear ka sa 4th gear tapus below 60kms takbo na gagaragal lalo if loaded w/ passenger....Anyway ayus naman sa akin performance ng VIOs ko 1.3E Mt.

Sir san ka bang casa nag ppayos.....malamang yong tumira o gumawa sa oto mo ay ojt's nila kaya nasira ang lug nut mo kasi hindi proper tool ginamit.....
Me kapag ppayos ako na punta ako sa repairing area nila ok naman yon basta pa alam ka lang sa visor nila sir.

Sorry sir forgot to mention, tachometer from 2k going to 3k or 4k. I usually overtake during 2nd gear and 3rd gear so dun ko rin naririnig. Iba talaga yung tunog niya sir eh sa normal na ingay ng makina ng vios so hindi siya noticeable kapag crusing speeds na (4th and 5th), pag hard accelerating lang talaga.

Pa check mo rin engine timing mo kung tama iyan konting bigay mo lang ng gas galit agad makina mo at hindi ka bibitin pag nagovertake ka.

Well actually kutob ko na rin yan. Share ko lang po, nung nagpalit kasi ako ng battery from stock, after initial start nagulat nalang ako at bumaba idle ng vios ko pero after driving it from LP to Manila, shockingly nag tune magisa yung engine at SEEMINGLY bumalik sa dati yung menor ko pero parang hindi na gaya nung normal (mababa pa rin compared dati).

I tried to inquire in CASA if they can check it together with my 20k PMS pero sabi nila hindi raw pede isabay sa PMS yun at kailangan paiwan which is hassle on my part. Hayz, I'll appreciate talaga kung matulungan niyo ko.

Sir for clarification lang po, garagal na sound (tunog truck) caused by high rpms on 2nd and 3rd gears po.

And about the lug nuts, hindi naman po siya actually sira, nalagyan lang ng 'markers' at hindi tinanggal. Tried removing kanina pero parang permanent T_T

Paps may RPM gauge ba iyang Vios mo ilang RPM mo sa 2nd and 3rd gear pag nag shift ka na nararamdaman mo ang garalgal na tunog.

Haha medyo mahirap talaga i-describe. Uhmm.. as I mentioned nga po hard acceleration on 2000 rpm and still increasing maririnig yung tunog truck. Uhmm sige bigyan ko po kayo ng situation... when i'm running on 35 kph on 2nd gear and suddenly decided to do hard acceleration causing my rpm to rise above 2000 and my speed to increase faster than normal (still on 2nd gear btw), dun evident yung sound. Same case on third gear. But after letting go off the accelerator and applied slight acceleration for crusing nalang, normal sound ng makina ng vios na.
