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.

As raz said, check the MAF sensor. Also, check to make sure the fuel pressure is within the manufacturer's specs. It may be weak.
