I saw your camaro5.com post about Engine Power is Reduced - Service Stabilitrak. My problem is very similar and happen about an hour ago. Lie you, I had a traction/ stability turned off and was in the middle of power braking/burnout. When the smoke cleared I had the same problem your describing. ANyways, what ever ended up happening. You said the next morning that the car ran better. Did the problem re-occur?
