Parang nabubulunan kapag tinotodo ung gas pedal

[eatmylens]

naeexperience ko to kapag tinotodo or at least near floor na ung gas pedal, as in parang napuputol ung daloy or nagpupugak pugak ung takbo nya. Pede kayang Spark Plug ang culprit?

Ano Sasakyan mo bro? EFI ba o Carburated?

It would help us to help you if you would mention what car and year/model you have and what recent work was done to it as well.

what fuel you are using?

[desert fox]

eto mahirap broGH, gusto nating mag-comment o mag-advice pero we are at lost, di sinasabi kumpletong specs ng sasakyan ng mga humihingi ng advice...

BroTS, balik ka dito oy....

kailan ka huling nagpalit ng fuel filter?
baka kasi kailangan na palitan o barado na.

double post.
(bumabagsak ang tsikot dito sa pc ko kasi.)

[tugasi]

you may try checking your distributor alignment (if applicable) and the condition of your spark plugs as well.

Ay sorry po, nakalimutan kong ilagay yung vehicle information. Anyway, it's a Toyota Corolla AE92 (Small body, 89mdl[?]) 4A-F/Carb. Sa Kuya ko kasi to medyo napabayaan na kasi nasa abroad na sya ngayon, kaya ako ung unti-onting nagpapa-ayos. I believe wala syang ginawang modifications sa engine lahat aesthetic mods lang.

Salamat po sa mga replies and info's given. Will definitely have a mechanic check its Fuel Filter and Distribution alignment. Regarding the fuel I'm using, I use a premium (Shell/Petron)

To be more specific regarding the "Pugak", ung bang parang my "papigil-pigil" sa buong koche na tipong mapapa-lean forward ka. Hindi sya ung tipo na parang tuloy tuloy parin ung takbo na parang nilagay mo lang sa neutral.

[eatmylens]

Additional info: Na-e-experience ko lang to kapag on "Gear" especially kapag nasa segunda (Or,at least mas madalas mangyari kapag naka segunda) kasi kahit i-todo rev ko ng naka neutral(Stationary) okay naman, kahit i-floor pa ung gas pedal.

baka nga sa fuel filter....otherwise sa fuel pump ito....

Check your carb and your carb jets. Shell and Petron fuels are E10 blended gasolines (except for Petron Blaze). Ethanol and carbs do not mix well and tends to damage the jets over time by erosion of the tip. Give it enough time, it affects the way the engine runs, causing over-rich mixtures.

It sounds like "sakal" ang carb. Baka barado "power circuit" or jet ng carb. Try mo bugahan ng carb cleaner ang carburador (tanggal ang air filter) then choke by hand para mag-flood ang gasoline at mahugasan baka sakali madala ang bara. Last option cleaning/overhaul ng carburator assy, you need repair kit.
additional sa mga suggestion above: check/clean filter dyan mismo sa supply fitting ng carb na kinakabitan ng fuel hose. Good luck

Sir kung sa fuel pump nga, bakit po kapag naka-kambyo lang nangyayari?

Siguro nga Carb ang problema. Took down all the informations you've given me and will try to DIY nalang muna at baka magawa ko instead of bringing it right away sa shop, baka masingil pa ako ng labor n 200+ na kaya ko naman palang gawin.

One thing tho, nabibili ba sa ACE/True Value hardware yang mga Carb Cleaner? another, when you say "Choke" yan ba ung hahatakin ko ung cable na nahahatak kapag inaapakan ung Gas Pedal?

Maraming Salamat mga Tsikoteers!

[eatmylens]

Ang pinagtataka ko lang bakit kapag tinotodo ung Gas pedal, eh dun lang sumusumpong ung problema?

[weisshorn]

"choke" ibig kung sabihin takpan mo ng kamay ang opening ng carb (without the air filter assy) habang ang isang kamay ay nirevolution ang makina. Ang pag takip ay pabigla-bigla para humigop ng maraming gasolina na maghuhugas ng carburador in addition sa previously sprayed carb cleaner. Gawin mo paulit ulit. Syempre controlin mo ang pagtakip ng kamay na hindi mamatay ang makina. Pag nasobrahan kasi ay mamatay ang makina, lunod sa gasolina. good luck

Pag tumatakbo ang car: during the time na ifloor mo ang accelerator syempre kailangan nya ng instant & additional power, ito at first ay iprovide pump na mag spurt ng gasoline then itutuloy ng gasoline flow via orifice (jet) na hinigop ng vacuum dahil nag increase ng opening throttle. kung barado ang jet syempre mauntol ang flow ng gasoline resulting to very lean fuel-air mixture kaya ang revolution ay pigil. Check mo rin kung mayroon spray ng gasoline pag bigla mo pinitik ang lever to increase rpm. Baka kasi sira ang plunger pump.
dagdag rin pala, check mo lahat ng vaccuum hose baka meron singaw o natanggal.

your air/fuel mixture might have been leaning out during this transition. if your plunger for your accelerator pump is stuck, or the ball check valve for it is stuck from sitting too long, the transition going to power mode will cause a temporary lean condition and the power circuit will be delayed more. another possible cause might be an ignition high voltage leak on the secondary side

[SiRbossR]

does your carb has a diaphragm? if it does try checking it. It may be damaged, loose or something might be clogging it.

[desert fox]

Sir kung sa fuel pump nga, bakit po kapag naka-kambyo lang nangyayari?

me clogged ang gaso mo somewhere....kaya ko nasabi na baka sa Fuel pump, baka di na din maganda ang return spring niya,....kaya di na maganda ang sipa ng pinakatiti nya....

try mo lahat ng payo ng mga katsikot sa itaas, nanjan lang yung solution sa pronblema mo...
