car is making noise cad.convertor is bad and abs light is on can someone tell me

scan test for abs codes,if the converter is making a noise you should have it replaced

Describe the noise in greater detail...The cats are warrantied for 80K but after that you'll spend $1,200 to replace it. What does one brake mean? Do you have any lights on in the instrument cluster? I doubt the ECU is bad. Call Milt's Service Garage in Vallejo to schedule an appointment and get her repaired. You're doing more damage right now.
