Slight jerks in corolla 1.3

aoa guys
i have corolla 1.3 with 2nzfe. It is running good Alhumdolellah but recently I have observed that after I let go my foot off throttle the car does not flow freely like it used to be. Slight jerks i can feel which only me on the control can feel. The passenger cant. You know that free moving like fluid feeling when u remove foot from gas pedal. It is not there. Rest no issues in car acceleration etc. The car also attain top speed without any struggle. No jerks on high speed. It is only in low speeds. I suspected plugs and changed them but issue is still there. Now i am suspecting fuel filter. People are saying that it is my weham. Some are saying that after driving cvt tranny car one feel like this on manual but my hunch is it is not weham. Something is there as I drove another manual which is normal.

Any idea. Should I go ahead with fuel filter or I am missing any point.

PS air filter is oem brand new installed in case u r wondering

Thanks in advance

Might be correct Well i guess you need to go step by step. get the air filter clean, clean throttle body, check the condition of your spark plugs, get checked fuel pressure. Make sure MAF sensor is properly screwed. Leave the fuel filter for the end step. I have heard people do get a little jerk in first gear. Even if i dont rev at 2000 rpm, mere sey yeh 10 th gen corolla band ho jati hai.

Change fuel filter with its element filter. It will cost you not more then 2000rs from market. No need to change complete assembly. Use liqui moly injector cleaner too when you will fit a new filter. When did you get throttle service?

Did he mention that ?

Just him that you are feeling slight jerk. And he will hopefully guard you better. Or you can go to any good electrician who understand these things. And update us after that

Goodluck

What's the problem here? I'm talking about complete fuel filter assembly. You need to change fuel filter at 80k kms max.

Sorry my bad I thought you were talking about engine assembly.

go for brake service and manual transmission oil change if not done already.
