My 2010 Escalade shows the Stabilitrak warning light and TCS

Customer Question

My 2010 Escalade shows the Stabilitrak warning light and TCS warning light. Sometimes, the engine almost shuts down. Then, it goes back to normal. It is becoming more frequent.
JA: Do you know the code? Did you check the fuses?
Customer: It is showing the TCS code and some others.
JA: Are you fixing your Escalade yourself? What have you tried so far?
Customer: No, a mobile mechanic did a diagnostic but wanted to start changing the spark plug wires. He never mentioned fuses or sensors like some of the forums mention.
JA: Anything else you want the mechanic to know before I connect you?
Customer: I suppose not.
