My Aveo takes spells that when you stop and start to move it creeps along. I can push the gas pedal all the way to the floor and it won’t go any faster and then all of a sudden it takes off and runs fine. No Service Engine light ever comes on and when I had it scanned they found no codes. Anybody else have that problem and know of a solution?

Your vehicle has a drive-by-wire throttle system.

Instead of having a throttle cable between the accelerator pedal and the throttle body, your vehicle has an accelerator pedal position sensor, which sends a signal to the computer, and the computer operates the electronic throttle body from that signal.

That’s the system you want to have checked out.
