The hypothetical reason why your car is jerking at speeds of over 55 MPH is probally due to the transmission slipping as it engages into a higher gear. If there is a hard shift of the transmission at higher speeds you may have to have the vehicle serviced soon. My car was doing this once and I had a tire out of round and ready to blow. I had the same problem. It was only when I took off at first, then when I was driving on the interstate it did it whenever I went over 55 mph and the cruise wouldn't work. I had to get the camshaft sensor replaced, and afterward I had no more problems.
low transmission fluid clogged fluid filter
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.
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
it is cauused by over accelaration during the car is in nutrule so if you accelerate at that point the cars belt will get old and it would proably that the reason you are getting a wretel in your car when you accelerate
It would be a transmission issue, not up shifting. If the engine is in "limp mode" it will not accelerate over a set mph.
it could be a number of things. my first guess would be brakes. when you say pull off, do you mean turn off to the side of the road/make a turn. or take off/accelerate from a stop
STICKING BRAKE CALIPER
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?
A car goes faster when you accelerate. It slows down when you brake.
There are several problems that could cause your car to jerk when slowing down. The most common cause would be a transmission problem.
I don't have a car.
could be failing transmission
He would wildly accelerate his car when the traffic light turned green. Gravity causes falling objects to accelerate as they move toward the Earth. Living in a foreign country can accelerate the speed at which you learn the native language.
That depends on what type of car you're driving. For example, a pickup truck would accelerate more slowly than a race car.
There are a number of reasons why a car would idle find but sputter when you accelerate. It could need a new spark plugs. You may also have to replace the filters. It might also be an issue with the air flow.
When a car turns a corner.
torqeconverter lock up its normal.
You could be pressing the brake pedal too hard. Another reason why it may jerk is because the pull brake is engaged.
Your car should not smoke when I accelerate. Maybe it caught fire because you dropped a cigarette. If my car smokes when I accelerate, it's because the piston rings are loose and oil is getting into the combustion chamber.
Only fuel. Somehow it is getting in there. Fuel metering needs to be looked over.
Is it bogging down? if thats what your referring to, then maybe try a fuel pump if yoir car has one.
