Check spark plugs
Check spark plug coil
Check air filter
Try pumping RON97
Oil filter and cat con won't affect performance, at least not that i know of

Also check tyre pressure, brakes. Maybe brakes rubbing?

Gearbox oil changed?
120 - -140 is easy task for the Swift

I find it too easy to hit the end of the meter

spark plug changed
spark plug coil - Need to check on this
Air filter - Need to check on this as well
I did try shell vpower = ron 97 ... I don't notice much of a difference.
Tyre pressure checked as well.
Gearbox oil - Need to check when was the last date or was it even changed before (Sorry newbie here, maybe my dad did have it changed before as it was maintained by him before this)
and yea 120 to 140 on a stock swift is easy.. actually going up to 170 is pretty easy as well.. however what I face is some times I feel like the car is struggling to climb when I floor the pedal but I still see the rpm meter around 3k rpm only. it Usually happens around 80 - 100 or 120 ?
Maybe it's the gearbox oil. Anyways will get it checked out and hopefully it solve the problem. And thanks for the advice !

PS : I notice there is screeching sound when I brake some times (usually when reversing out of the house or going down a car park slope), is it the brake pad or brake disc problem ? my dad's altis has similiar issue as well. Even my friend's subaru has the screeching sound when brake but he told me its normal for his car ?

Anyone experience this as well?
