What causes a car to hesitate during acceleration?
The Most Common Causes of Hesitation: 1 Bad throttle position sensor 2 Ignition system problem 3 Fuel system problem 4 Vacuum leak 5 Bad accelerator system (carburetor models)
What happens when you step on the gas to accelerate?
When you go to step on the gas pedal to accelerate, you will suddenly feel like the power has been lost in the engine for a couple of seconds. Instead of going faster by stepping on the accelerator pedal, the speed will be reduced.
Why does my car vibrate when I accelerate?
So remember these when your car vibrates when accelerating. You may find damaged bearings in cars that have been driven extensively for many years. If you feel the rumbling through the steering wheel, the problem could arise from plenty of components – struts, bearings, shock absorbers, tie rods, and ball joints. #5. Stuck Brake Caliper
What’s the problem with stumble on fast acceleration?
The car starts, idles and runs ok under gentle acceleration. My problem is a severe stumble on fast acceleration that does not resolve no matter how much adjustment I make to Accel Pump, or Fast Accel inputs. Current settings are Accel Pump 170 = 25.0 and Fast Accel 170 = 50.0

What should fuel pressure be during fast acceleration?
The stumbles I feel are confirmed in the log files as a very lean spike on acceleration followed immediately by a very rich condition. I installed a pressure gauge at the inlet, behind the filters and fuel pressure is at 55 psi, increases to 60 psi during fast acceleration.
