2001 Hyundai Santro engine miss fire while engine start but

Do you have a check engine light and when was the last tune-up, don't recall give it a tune and see what happens

Engine misfiring can be caused by worn or fouled spark plugs, a weak spark (weak coil, bad spark plug wire), loss of compression, vacuum leaks, anything that causes an unusually lean fuel mixture (lean misfire), an EGR valve that is stuck open, dirty fuel injectors, low fuel pressure, or even bad fuel.
