because your transmission is going bad if it is stick let off the clutch slower but if it is automatic then your trans. is going.
you are going too slow for that gear your engine has very little torque at low rpm
You could have ignition problems if it is the engine causing the jerk.
Poor driver or bad transmission.
You will feel a jerk from the engine / transmission when putting in gear. This can inturn damage the CV shafts.
turn the engine off
Its normal for most manual cars the clutch is basically shifting gears in the engine but if you are accelrating shifting gears higher it could jerk a little bit so it can lock the gear and preset the engine to the desired gear Now if this is an automatic here you are not hitting the brake pedal fully Transmission fluid is low or empty Or it can be just old so it can jerk a bit to get into gear... however it is potentially bad for an automatic car because it has more parts and the thing it would do the most harm to is the gearbox.
Try a basic tune up. New spark plugs, wires, cap and rotor. When the vehicle is in first gear and you are accelerating, that is when the most load is on the engine. It sounds as though under a load, you are losing your spark because it is arcing out where it should not be.
Trouble code P0731 means: Incorrect gear ratio, first gear
When shifting from first to second gear in a manual transmission vehicle, you need to press the clutch pedal to disengage the engine from the transmission. Then, while keeping the clutch pedal depressed, move the gear shifter from first gear to second gear. Finally, release the clutch pedal slowly while simultaneously pressing the gas pedal to smoothly engage the engine with the transmission in second gear.
change the map sensor
Because this puts the least strain on the engine.
1. Put the engine in a lower gear and leave the clutch slowly. Vehicle will stop with a jerk. 2. Use parking brakes
