The ABS light and the ETS light on my 1998 Cavalier stay on after it is startedwhy is that?

I am having the same problem and sometimes it stalls my car. It started shaking a lot when i tried to turn it on this morning and i had to pump the gas a few times, i read this.

I would have a mechanic remove each ABS sensor, using an external torx wrench, and clean it with a spritziled rag (don't use compressed air). Should be a very simple job. See if this solves the problem before doing anything else.

My experience with other people, who have had the ETS light come on, is that it often indicates a weak ignition system. Begin by replacing the platinum spark plugs with the exact ACDelco plugs that came in the car (likely Part No. 41-928). Also, replace the fuel filter.
