Jerks at low constant speed

[pwuser160724063317]

Aoa
I have suzuki alto lepo 1999 impoted japnese variant. The issue i am facing is that it gives hard jerks at constant light accelerator. It seems like the power is cut off from the accelerator for some time. Then it comes back in full power. Then it's gone again. The jerks are gone when i press the accelerator hard. Also these jerks happen when i have just started the car and begin to drive. They are gone after a while.
Another thing is that it takes two ignitions(self) to start.
I have already done tuning, changed spark plugs, changed coils, gotten the current checked, changed computer, changed fuel pump, changed air filter.
Any expert opinions?

its probably drive by wire system has some carbon in it.

the accelerator pedal needs to be opened and there is a sensor underneath which needs to be cleaned. should fix the issue.

i am assuming that the car is efi.

if its carburator based than the troubleshooting is more related to jets.

share pictures it would be helpful to guide.

Yes the car is efi. Sure will try.

ok thanks. please get the accelerator sensor cleaned. its along side the pedal if i am not wrong.

also regarding 2 self start and jerks, both of these things might be related to timing. please get it checked and set up correctly.
