Why does my car decelerate when I let off the gas?
A stuck or binding throttle plate, either as a result of grime, or a faulty throttle body motor can produce the symptoms you are experiencing. Worn motor mounts can also produce similar symptoms. Worn mounts can cause the vehicle to jerk as a result of the engine moving back and forth in the engine bay.
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.
Why do you take your foot off the gas pedal?
It’s entirely possible, but at the expense of mileage. Much of driving is taking the foot off of the pedal and then reaccelerating. 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.
Why does my car slow down when I let go of the gas?
Yeah, its a combination of rolling and aero resistance. If you feel something is off you can check the air pressure in all 4 tires and go a step further by jacking up each corner and see if they rotate freely. If you arent into jacking your car another test is to feel how warm the wheels are after a drive.
Is it better to drive without giving the car gas?
The more a car coasts without giving it gas the better – you save gas. I would say that your driving habits are based on experience with mostly manual transmissions – you get used to lifting off the gas at a certain distance before the light. I’m the opposite – I’ve driven mostly automatics.
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.
