Ok. My Chevy Tahoe was running fine on the highway at about 70 mph, when all of a sudden the service traction control, and stabiltrack off warning lights came on . At the same time the engine light started flashing and the engine started acting funny. Once I got off the highway and was at the light the engine felt like it was misfiring? And acceleration was slow. I've read this could be the throttle body sensor. Has anyone else had this issue? Again it's a 08 Tahoe Z71 4x4 5.3. Any info is greatly appreciated...
