Hi, I just found this newsgroup and was wondering if someone has any expert opinions. I have a 96 civic si (canadian) (US is ex) 127 hp sohc vtec with 162k km (~100k miles) standard trans, When pressing harder on gas pedal during acceleration it feels like it hesitates a bit (like bicycle chain slipping or tires not gripping on snow). That is mostly in low rpms <3000 ( high rpms too, but not as much) and when I let go of the pedal a bit the acceleration kicks in again. Anyone have any opinions or thoughts before I take it in to a mechanic? Thanks all
