Q: Stabilitrak and traction control
When at idle at a stoplight, idle becomes really rough, and service stabilitrak and traction control messages and warning lights come on. When increasing the RPM to 1000 or over after about 30 seconds the lights and messages go away. But the idle remains rough. Check engine light comes on and when checking the code, it is a misfire in cylinder 2. I have already changed the coil, wire & plug for this cylinder, but it still keeps happening. What can be causing this?
