What happens when you take your foot off the gas?
I guess I should watch the tachometer when I take my foot off the gas. If it does slow down to idle (750RPM), then I shall have to agree with you. But if the fuel injection keeps the engine RPM close to what it was with my foot on the pedal, then there is room for correction.
What happens when you lift off the gas pedal?
The APP sensor essentially tells your engine how fast or slow to drive when you press the gas pedal. When you press down or lift off the throttle, it sends an electrical signal to the vehicle’s engine control unit (ECU), and then transmits that signal to the fuel system.
Why is there no deceleration with foot off gas?
The more inertia is carried is the less energy will be used reaccelerating. manufacturers are driven by CAFE mandates and the market forces to design cars that will get maximum gas mileage for their class. I’m actually rethinking what I said earlier.
What happens when you put your foot on the gas?
The fuel injection system does nothing until the engine is turning (starting or running), so pressing the pedal before you start will make no difference. The fuel injectors work at any RPM, so a choke is not necessary. The computer simply feeds a little extra gas through the fuel injectors to start the engine.
What makes a grinding noise when you let off the gas?
With the car in park engine running slowly rev it up to about highway speed (2,000 – 2,500 rpm) and let it back down slowly to idle and see if you can reproduce the noise while sitting still. have you ever had any axle work or cracked axle boots?
What makes a weird noise when you press on the gas pedal?
Q: When I press on gas pedal it makes a weird noise til you let off it. Gas pedal makes this noise when your foot is on gas pedal and there is a slow take off especially if u stop a light for a moment when its your turn to go my truck moves so then catch speed
What happens when I let off the gas?
When I get over 60 mph and let off of the gas there is a grinding/rattling noise. It is very loud, but doesn’t seem to affect anything as far as power/performance. If I press the gas pedal it goes away, but as soon as I take my foot off the gas it is back. Once my speed gets below 60 mph the noise is gone.
While cruising at any given speed, I will come to a stop sign or red light or a situation that causes me to take my foot off the gas. The idle will stay at whatever the cruising idle was for about 2 seconds, then increase a couple hundred RPMs, then come down to the normal RPM. The car actually accelerates a tiny bit with my foot off the gas.
What is the stopping distance at 60 mph?
Virtually all current production vehicles’ published road braking performance tests indicate stopping distances from 60 mph that are typically 120 to 140 feet, slightly less than half of the projected safety distances.
When does your car shake when you let off the gas?
Q: My car shakes when I accelerate, but stops once I let off the gas. When I drive my car as I accelerate above 25 MPH my vehicle begins to shake. This shaking continues at all speeds above that point, but once I let off the gas the shaking stops regardless of my speed.
How to calculate the stopping distance of a vehicle?
To determine how long it will take a driver to stop a vehicle, assuming a constant rate of deceleration, the process is to divide the initial velocity (in fps) by the rate of deceleration. You may want to use our Vehicle Stopping Distance Calculatorto do actual model calculations. 60 MPH = 88 fps. (fps=1.467 * MPH).

What’s the average stopping distance for a car?
In this case, this works out to be .5 * 88 * 4.4 = 193.6 feet, plus a reaction time of either 88 feet for a second delay in reaction time, or 176 feet for two seconds reaction time. That yields 281.6 feet or 369.6 when added to the base stopping distance of 193.6 feet.
What happens when you let go of the gas?
When I drive, let go of the gas, I can feel the car slow down as if I was pressing the brakes lightly. If I don’t have to stop completely for a while, I’ll let it keep going and then I’ll feel it get “unstuck” and I’m coasting with little slowdown feeling.
