Pick Reduced after 65K maintenance

[management.techopk]

Respected Pak wheelers,
I recently bought Toyota corolla 2016 Auto in October 19 It was previously 35K driven and Up till now the mileage is 68K. It was Toyota eastern maintained after 65K maintenance
These Things were checked and replaced : -

Spark plugs
ATF replace
Brake pad replaced
Injectors service
Catalytic cleaning

Someone also told me to change the fuel filter as well which i was unable to .

The pick is reduced at certain gears probably 1 or 2 but after going above 60 the car feels perfectly fine.

And someone told me to change the Gear oil filter but my mechanic said its not necessary and just replace the ATF.

doesnt make sense
car was serviced from company
and after all the mentioned things
car should drive much better

not sure if fake or inferior plugs can be ruled out here
or if cat was further blocked
as far as i know
company only blows in air in cat. they dont use any liquid

[hash4u]

if by any chance u hv oem plugs and did not dispose them
put them back and check

Spark plug was change on 35K and when I ask the mechenic to change them he said they look all fine

[hash4u]

pour 1 tin with fuel refill
it might help with any negligence left in servicing

try using hi octane complete tank at high rpm level

Probably related to wrong installation of cat sensors after cleaning. get it checked and re fitted properly. car is probably getting wrong response from the sensors and this is causing the throttle response to be sluggish..

already did but did not felt any kind of difference and i tried driving it on D-3 and D-2 but the RPM is not going above 2K RPM

[management.techopk]

I have already booked the appointment will be doing that soon

[MADDYBOY2]

Update: Some Sensor was not placed correctly that's why the pick was reduced although i did not get any kind of Engine light
Now the car is perfectly fine
Thank you everyone
@Thinking Thanks a lot for reminding me about the sensors
