i have a 1999 z71 with the 5.3. when i am driving and reach 45 mph my truck starts to buck and it seems like it is in the motor. when i give it more gas it stops or when i give steady pressure on the gas it does not do it. the only time that it does do it is when i am always going 45 or when i go past 45 slowely. has any one else had this problem and how did you fix it
