i have a honda civic so4 with d16a non vtec inside..auto transmission..
-recently my car is having jerking problem at 3-4rpm..firstly i suspected it might be missfire problem.so i replaced new plug cable,spark plug,distributor cap..but the problem remains,i even swap another distributor as well as ecu,but it still remains.
-later i tried to use ron97 fuel and the jerking problem gone.but after 3days it started to happens again.fuel consumption also bad..full tank of ron97 only able to get 350km.
-rpm idling is just ok..maintain on 900rpm..but when moving,it will jerk at 3k-4k rpm..when cruising,the jerk will happen sometimes.
-so now im suspecting the fuel mechanical is in fault..either the throttle body,fuel filter,or injector?
pleasee help me..
