that whole post can be reduced to

asking the blind why your car jerks,is near
impossible, ask the living, person in your service shop this and win.

nor do we have "wiki"
:The Maruti Suzuki Swift was launched in India in May 2005 with a 1.3-litre petrol engine:"

Gross engine misfiring , petrol engines.

get a tuneup, spark, filters?
m13 engine needs good spark to burn all fuel.
try at least spark plugs, they do not last life of any engine.

btw,
misfire has over 50 causes
in a shop there are 1 to 10 tests
to discover true cause
they dont guess, they test.
or go broke (after doing a tuneup, gee)

I would start with checking the fluid level in the transmission.

With the vehicle on a level surface start it and let it run in park. Pull the transmission dipstick wipe it clean, reinsert and pull it out. If the fluid is not in the cross hatch area add 1/2 quart of ATF+4 and recheck the fluid level (it will take a couple of minutes for the fluid to settle out of the dipstick tube). Continue adding 1/2 quart at a time until the level is in the cross hatch area.

With your foot on the brake run the transmission through all the gears. place the transmission in park and recheck the level, adding as necessary.

Then drive it and see what happens.

The first place i would look at is the heater blower motor resistor these are known to over heat the wire connector that plug into them.And if your heater fan is only coming on with 1 speed or none at all then you will need to replace the resistor.Go to www.rockauto.com for the best price on these parts.

the engine was flooded probly fuel regulator is bad

check for a loose ground to the engine

may have a leaky cold start valve injector

try taking off the gas cap and then retighten it.may have a vacume lock.make sure gas cap is tight.

is it burning oil or losing oil,driving it without oil may have damaged it,and putting too much oil and driving it may have pop the crank seals,inspect engine,decide what to do,not agood sign for motor,

Probably you petrol tank blew.
