if it tends to sputter and have no power i would suggest the fuel pump. it it is only after the car has warmed up, or a while after you start driving it might be the ignition module.
1996 Chevrolet cavalier shuts off while driving and have to put in natural or park to restart
Have someone check your fuel pump pressure,if you lose fuel pressure while driving,and then it comes back that would explain why it seems to start by itself.
While driving my cavalier will shift into high gear for at least a couple of minutes. Shifting gears,giving it gas does not help. Any suggestions?
blown engine, out of gas janitorial duties.
Wheel bearing
Replace the fuel filter, that is a good place to start.
If memory serves me right, you press in on the collar at the cylinder and hold it in while you pull on the line.
I'd check the coolant level first, then the thermostat.
What can cause the RPM on a car to jump while driving is a problem with the transmission. It could be a problem with the gears in the transmission itself.
Wheel bearings and allignment. Can be tires as well and sometimes even a bad motor mount.
If you mean the light it should reset itself while driving
It will reset itself while driving if pressure in spec and sensor itself is not bad
