In first and second, sometimes but usually not third, if I floor it, the car will start pulling, then about halfway up the tach start occasionally bucking HARD. I can do full throttle pulls to 7k in forth just fine. Lights on the dash act up as this happens as well. 1999 nb stock drivetrain. Searched around and just found threads on low speed bucking, my car is fine at all speeds at lower throttle levels, only bucking during hard pulls. Thinking plug wires rn? Also knock sensor is bad but not sure that that would cause this? Sorry for the boring diag thread, broke college student atm, once I finish school I'm gunna try to have a cool build thread for you guys but just not in the cards rn. Thanks in advance for any and all help.

 

It was loose spark plug wires
hopefully if anyone else has the same issue google will lead them here
