Hello, I have 89 camaro. I replaced starter and changed oil for while ago. But, today my car started to jerk when I drive. fuel pump or engine problem?? If you have any idea, please let me know. thank you

Are you getting any trouble codes from the ECM, before the car cuts off or starts to jerk?

mine jerks alot too !
I just gotta keep a steady foot on the gas!

It could be any number of things wrong with your camaro.
youll need to do some more troubleshooting so that we have more info.

is it a hesitation or a pulling foward kinda jerk????? Need more details

Thank you for your responds. I think I have pulling foward jerks. It happens, especially when I hit the gas. A tachometer jerks too.
sometimes, it doesn't jerk but it usually jerk

It sounds like you might have a transmission problem (Trans mount) or a drivetrain problem. Check your U-joints and see if they are loose.

check out the fuel filter back by the tank probably about a foot and a half from the tank toward the moter , if thats not it then pull the tank and check the strainer on the fuel pump , Also if those aren't your problem you should have your Mass air flow sensor checked and also your throttle possition sensor which is on the throttle body itself and has a three pronge plug its on the passengers side of the throttle body. Bad plugs , wires and distrbiutor cap will cause that too. Hope this helps

My wife says there is a jerk in my camaro also!:)

It sounds like a loose coil wire or a bad ground to me.

The problem solved. A problme was some of ignitoin wires. I replaced them, now it doesn't jerk anymore. Thank you.
