I have been noticing for many days. My car is getting jerk during slow acceleration, but it vanishes at hard acceleration.
The jerking starts near around 30 to 40 at 2000 rpm.
No check light found.
any expert suggestion????
i had the same problem in my swift... found out that coil wire was faulty , changed it and there was oil in plugs well, so had to change valve cover gasket .. problem solved !
