Check your MAF and O2 sensors. One of them is providing an incorrect reading at low speeds

[uzair3337]

On visual inspection MAF sensor looks clean.
But its Toyota Denso written on it.
Could it be the reason.
I bought the car few months back.so dont know the history

I live in District Khushab Punjab.
Near Sargodha

[uzair3337]

Yeah a few people on the Swift forum have advised me that too.
But i am curious that why it does the same behaviour in Neutral standing still.
Clutch depressed or pressed in both situations.
When i blip the throttle.
Rpm goes down engine shakes a bit and than it goes up.
But when the rpm are above 1000 and i again bip the throttle RPM goes up perfectly.

This might be the reason.
But the gears shift buttery smooth.
From 1 to 5 and Reverse.
No issues getting in or out of gear.
No grinding noise.
The other thing is that it is a waste spark system
And NGK Copper plugs are in it.
It might have worn the coils out.

By the tank method.it gives me 500+-30km on 37 liters.and i wait for the temp needle to cross C line every morning before i start driving it.
And start pushing it after it reaches optimal Temp.
Thats about 13.5 km.without A/C
Which is pretty good
On daily commute of about 50km.
In the rural areas where i can barely go in 5th gear.
Mostly 3-4.
But the roads are good.With lots of traffic.it coasts pretty good In neutral too.

What should i look for during scanning.
Here even the suzuki guys dont know about trims and ECU related stuff.
The other thing is that when i mix Hi Octane 30/70 ratio.
Issue goes away by 90%.
Sound of the engine improves alot.
Pick improves.
Could exessive carbon buildup in the chamber be the reason?
But milage is 80k.
And nowhere from the body or interior it looks like its a high milage car.
Its in immaculate condition MA.

[dayrider]

If high octane fixes your issue. Change your fuel station , it's selling dirty fuel
