toyota camry 95 引擎 chok下chok下

睇嚟係你d filters (油隔 / 風隔) 太舊無換.
當d filters 太舊塞住哂, d燃油唔夠空氣爆炸, 令你引擎一時有力一時無力, 就會疾吓疾吓. 當你加速時, 泵油量大咗同入風多咗, 就無事. 減速時, 無燃油泵入去爆炸, 所以亦唔會疾油. 但在一個速度時就有問題.
試吓換咗d filters啦.
同埋記得定期check車. 唔check車由小問題變大問題要整重貴!

your AT using the lock up mode when speed around 60 miles/h (80km/hr)
meant the engine direct transmit the power to transmission ( by pass the torque convertor) gear teeth and then to drive shaft.
which will much more fuel economy then before. so the engine rpm a little bit drop down (150 rpm), at the lock up mode, you would not see the engine rpm rise when you step on the gas, it seem the pointer not move ( speed 60 miles/hr)
except 1/2 throttle or pressed the brake pedal, the lock up will release.
the engine rpm pointer will move again.
once AT lock up , normal driving on paved road, so run through the incline 1 to 3 degree will felt the engine chok or pulsation movet ( this pulsation came from the transmission torque convertor)
Normal-read the catlogue specification of your car AT with lock up this wording.
latest model also have this wording.
no need to repair
it happen around 60 miles/h with light throttle opening- AT lock up mode
<60 miles lock up release
> full throttle, 3/4 throttle, 1/2 throttle, press the brake will release.
