Well if its an automatic, that's easy... I have this too. first answer this...
how fast are you going?
does it have overdrive (auto only)?
if manual what gear you get up to when this happens?
well if its auto, and your going fairly fast and suddenly let go of the gas... its going to change down quite quick due to gearbox design. This would give the sensation of the car braking...
if its a manual car, then you are most likely in too low a gear to start with, this is why we change down when we loose our brakes, speed reduction is effective immedeatly without brakes...it slows you down to save emergency speed...1 min or so.AnswerI am having a similar problem with my grand am! I have been told that it could be a motor mount AnswerMy 1993 Buick Skylark had the same problem last year-- if I took it above about 40mph after the engine was warmed up, every deceleration thereafter caused the car to shudder. After researching it a bit, I decided it was probably the Torque Converter Clutch Solenoid in the automatic transmission, so I had it replaced and the problem disappeared. I've read that this is a somewhat common problem with Overdrive, which my car does not have, so apparently the problem doesn't play favorites.
a small evap leak would not cause your car to jerk.
would an automatic transmission car jerk when shifting after having had a transmission flush
One of the possible causes of a Pontiac Bonneville to jerk during acceleration is that the car needs a tune up. The engine misfiring can lead it to jerk as you accelerate.
There are several problems that could cause your car to jerk when slowing down. The most common cause would be a transmission problem.
What kind of car is is? When it jerk while shutting off, do you turn the key off and it sits there chugging for a second before stopping?
STICKING BRAKE CALIPER
try changing plugs and wires
a car approching a redd light
Deceleration is a decrease in speed. Such as a car slowing down.Braking your car as you approach a red traffic light. A bird coming into land needs to decelerate.
could be failing transmission
Is stepping on the brakes of a car acceleration. That would be deceleration.
You could be pressing the brake pedal too hard. Another reason why it may jerk is because the pull brake is engaged.
torqeconverter lock up its normal.
It COULD be a motor mount or worn suspension component.
The speed of the vehicle before deceleration or braking.
A car approaching a red light.
Could be as simple as a tune up.
If you have a front-wheel-drive car, the first thing I would check would be the Constant Velocity (CV) joints.
Noun: The jerk of the car sent the groceries everywhere. Verb: That door sticks, you have to jerk it open.
Deceleration opposite of acceleration
The deceleration is 5 metres per second per second or 5 ms-2
Both can cause it.
rev limiter will only let the RPM's get so high then it cuts back
Do you mean JERK?
