toyota corolla 1.6 gli HESITATION in ACCELERATION problem

[Karl Engbino]

Hi tsikot members,

I need help. Hirap mag accelerate at humina ang hatak ng sasakyan ko. Automatic transmision ng oto ko and almost parehas lang sa corolla ang engine, transmission model at iba pa.

Elaborate ko lang problema, bigla humina ung hatak ng sasakyan. Dati kasi as in magaan lang apak ko sa gas kasi malakas nga hatak nya, at mabilis mag accelerate. Tapos one time biglang humina ung hatak, ewan ko kung ano ung nasira. Ang malala pa nun di na nakakaakyat ng ramp ung sasakyan (happened in galleria, guards had to push the car uphill while my foot was flooring the gas pedal).

I did my research at ginawa ko ang mga ito na akala ko maaayos ung acceleration problem ng sasakyan ko
-changed fuel filter
-cleaned maf sensor
-air filter is in good condition
-cleaned throttle body
-clean throttle tube (ung malaking tube from air filter to throttle body)
-cleaned throttle position sensor
-changed my ATF (drain and refill method)
-changed AT filter
-cleaned AT oil pan and magnets
-changed spark plugs
-adjusted the accelerator cable (base from manual)

After nito lahat andun pa din ung problem, ang tagal mag accelerate kahit naka floor n ung gas pedal ko, pag nasa third gear na ako, kailangan napakataas ng rev ko para lang magshift to 4th gear. Hindi naman nailaw check engine ko.

Saan ako nagkulang, saan?! T.T

i don't know if your car still has these, but in older cars... advancer mechanism might be non-functional.
1. your vacuum hose to the distributor may have a leak.
2. something loosened in your distributor.

Have you ever checked and inspected your brakes and hand brakes? When was the last time you did inspecting them, a year, one and one-half year, or two years? Minsan di na natin napupuna ang pumipigil sa acceleration natin ay yung preno. Na naninikip na, di na na-release pagbitaw natin ng preno. Mapupuna na lang natin minsan, dahil sa umuusok na ang rim at brakes assembly dahil sa sobrang init. Kapag nananakbo ang sasakyan mo ba, at binitawan mo ba ang gas sa pedal, na-freewheel ba ang takbo mo, o dahan dahan ka humuhinto? Kapag dahan dahan ka humihinto, pa-check mo muna preno. Minsan naka focus tayo sa harangkada masyado, kung papaano tutulin o bibilis, pero ang humahadlang sa ating pananakbo ay paninikip ng preno. Opinyon ko lang.

Rapide nga naman oo

Adjustment ng timing dalhin mo sya sa may gamit na timing light.
And yes pag medyo off ang timing it can cause hesitation sa acceleration

It is certainly true.

Expected na ang violent reaction sa Rapide dito. May dedicated thread sila dito ng mga horror stories na dumami sira pagkatapos nila gawin...

Sa price na lang ng timing adjustment meron tumatanggap nyan 300 lang eh...

Magkano nga ulit hinihingi sa iyo? :-)

[rodetor]

Better check also timing belt before going to set Basic Ignition Timing with a timing light. After mo mare-assure na naka-set sa tama ang Timing Belt sa head cam at crank pulley, set adjust ka na rin muna ng Valve Clearance sa factory setting. Then, matapos ma-sure ang mga setting na nabanggit, tsaka mo gawin i-check at adjust Basic Ignition Timing with a timing light.

Hi Guys,

Sana may makarelate sa problem sa car ko. nababasa ko sa internet, parang common problem daw to.
Kapag tinatapakan ko gas ng mabagal, parang ok lang ung pag-accelerate. nagrerev ng maayos.
Pero kapag driving na, sympre, kapag magcchange gear, kailangan mo mabilisan pagtapak ng gas.
Ang problem, kapag mabilisang pagtapak ng gas, hindi kumagat yung gas. parang may hesitation sa pag accelerate.
Kailangan mo pa bitawan ulit ung gas and try timplahin yung pagtapak para magaccelerate.
Sana nagets niyo problem ko guys.
Ano kaya pwedeng icheck, kapapalit lang po kasi ng starter, MAP Sensor, spark plugs.

The coolant temperature sensor is used to measure the temperature of the engine coolant of an internal combustion engine. The readings from this sensor are then fed back to the engine control unit (ECU), which uses this data to adjust the fuel injection and ignition timing.
