this has been a problem that has been going on from the beginning. the timing can not keep up with your foot. when you press the gas, the timing adjust to accommodate. G. M. has found a solution, VARIABLE TIMING. it adjust on the fly, it is hydraulic controlled, using the motor oil. it is not easy to work on, needs special tools and training, but it works great. this feature it part of the new VORTEC ENGINE.
Tires and/or wheels may be out of balance
It sounds like u need to replace the thermostat. At slower speeds the air flow through the radiator is minimal, but at higher speeds the air cools the radiator more. This only happens if the thermostat is not keeping the water in the engine block long enough.
Falter is to hesitate as conceal is to disguise or hide, because falter is a synonym of hesitate and disguise or hide would be synonyms of conceal.
if your car shakes while driving and gets worse at higher speeds usually means the tires need to be balanced and if tire damage (cupping) has already started your gonna have to replace the bad tires
why would a 2003 Monte Carlo hesitate between 30-45 mph
Billy was hesitant when he was asked a personal question.
Would help to know what type/size of carb, distributor, cam, year of vehicle and what mods.Most important is what cam, if stock or a performance after market.some causes could bebad accelerator pump ( in carb)weak fuel pumpbad gaslow float levelbad advance in dist (vacuum or centrifugal)plugged air cleanerplugged exhaust ( bad cat conv plugged muffler)See why need more info?
A faulty fuel pump would cause your Navigator to hesitate when you accelerate. Bad gasoline could also be at fault.
it would most likely be the bearings but in some cases sometimes the axle make a humming noise when traveling at high speeds.(front wheel drive)
The molecules of a gas move faster at higher temperatures, which therefore speeds up diffusion.

Yeah I don't like to hesitate it
