hi i am shannon i will help on this issue
if you feel the abs pulsing the brakes. you may have a wheel speed sensor that is starting to go bad.
the only way to confrim that is to read the wheel data .when stoping
i would take it to a tech that can reed daewood abs data
he will also retrive the codes that are keeping your engine light on
he should not charge you more than 1 hour labor.
for the diagnoise and give you a estament for the repair.
if he dose find a bad wheel sensor you can replace it your self .to save $$$
you really don't need a daewoo tech just someone with a scanner that can read abs data. hear is one that will read all the data in your daewoo.
please chack out there web site
