Why would a 1995 Monte Carlo stutter?

Answer 1

when does it happen? what motor do you have.on the 3.8 motors some times the tps at speeds of 60 and above cant refresh quick enough.when the throttle valve is closed there is a reference voltage of 5v. as you check it with a dvm and open the throttle valve the voltage should steadly increese. if not try cleaning the contacts, shorts poor connections ect if this dosnt work it might be the tps
