Tsikoteers help naman.
Last sunday while driving sa highway, biglang-bigla on accelerating and pedalling on the gas parang nag-stumble yung engine (kumakadyot). Tapos bumababa yung rpm kahit nasa 4th or 5th gear, and nabawasan yun power. Parang walang acceleration pagtapak ng gas. Intermittently, pakadyot kadyot ONLY when stepping on the gas to accelerate to overtake o pagakyat.
Today, normal starting naman, wala redondo on starting up di na nagstumble pero yung loss of power pagtapak sa gas very noticeable, parang i am stepping on a sponge.
Can this be spark plug prob? (last replacement is 2 years ago) or fuel pump or fuek filter?
Any ideas?
