Hi I'm from Peshawar and recently I bought a PKDM Alto VXR which was swapped with following:

Engine - K6A engine
Gear - 4speed automatic transmission
ECU / Computer - E2 (33920 75HK0)

Car use to run very sluggish. Did the usual like cleaned throttle body, plugs, injectors, air filter, used profikar engine flush and 10w-30 mobil oil. Acceleration somewhat improved but it still runs sluggish with AC. Fuel consumption with AC is 6.2km/Litre which is alarmingly high. The 02 sensor was also cleansed however the dholki it screws into was without a filter / jaali. Now I'm not sure if there's any filter present by default and what its function is.

I took the car to few mechanics/ electrician and none gave a convincing answer. So here I am looking for any leads or help that anyone can give as this was bought to be driven in city but its becoming a burden due to its fuel consumption.

I am not sure that whether you are talking about that PKDM Alto, which was 1000 cc, and introduced many years ago.

If YES, then ye issues to hoon hi gey.

660 cc cars are already sluggish and underpowered. And if you are going to use 660 cc engine in a car, which is designed for 1000 cc (considering its body weight, etc.), then you will never be satisfied.

Fuell efficiency will be less, and car will be sluggish, due to less engine power and torque, and more weight of body, i.e. less power:weight ratio.

Tuning, etc. will not work in this case.

None will be able to give, as lots of unrealistic changes have been made with the car.

Sir its a PKDM ALTO VXR whose engine and gear was swapped with Japanese ALTO VXR engine. Japanese ALTO VXR comes with the same engine and probably same body weight. I think body weight ratio is not an issue since many heavy jap cars like wagon r come with these engines.
