I have a 2003 CTS. Every now and then it will drive fine

Customer Question

Hello. I have a 2003 CTS. Every now and then it will drive fine until the tc light turns on. Then it is like the car just doesn't go. I can push the gas and nothing. I have left it running in my driveway to see what it would do and once the light turns on, the car dies. It does ha e an after market radio that was in it when we purchased it. What could it be?!
JA: Just to clarify, what are the exact lights you're talking about?
Customer: The TC light on the dash. The traction control
JA: Are you hoping to fix this yourself? What have you tried so far?
Customer: Yes wanting to fix it myself. We have tried looking to see if anything was loose and there were some hoses that were loose and there was one, not sure which one it was. My husband said it was a vacuum line so we popes that back in and nothing. We changed the oil yesterday and today that stupid light does not turn off so we are unable to use the car. We have disconnected the battery to reset, and no help.
JA: Anything else you think the mechanic should know?
Customer: even pushing the traction control button doesn't help. The light will not turn on or off when pushed.
