Hi - my 1998 Nissan Truck Z24 - (4 cylinder) 8 sparkplugs starts fine, idles fine - but when driving and particularly when accelerating it bucks and loses power - when I relax the accelerator is seems fine. If I drive with accelerator minimally depressed it drives on - but the minute I depress to go on the highway or climb a hill it reacts and hesitates and bucks - any thoughts: Has recent tuneup and new fuel filter. Thanks Chris.
