I HAVE A 2007 NEW BODY STYLE SILVERADO 1500 WITH THE 4.8 LITER. FOR SOME TIME NOW I HAVE HAD THE ISSUE WITH THE STABILITRAC LIGHT AND SEVICE TRACTION CONTROL MESSAGE COMING UP. IT ONLY DOES IT WHEN THE TRUCK IS AT IDLE, AT A STOP LIGHT ECT... WHEN THIS HAPPENS AND YOU ACCEL THE TRANSMISSION SHIFTS LIKE A DRAGSTER FROM FIRST TO SECOND GEAR AND THEN LIGHTS GO OFF AND TRUCK RUNS FINE. THE CHECK ENGINE LIGHT ALSO FLASHES WHEN THE MESSAGE COMES UP. THE CHECK ENGINE LIGHT STAYS ON ALL THE TIME. I HAVE READ MANY FORUMS ON THIS ISSUE AND HAVE GOT 100s OF DIFFERENT ANSWERS. THE ONLY AFTER MARKET PART I HAVE IS A COLD INDUCTION K&N FILTER. I WOULD TURN TO THIS BUT ITS BEEN ON THERE SINCE THE TRUCK WAS NEW. IT NOW HAS 150,000 MILES ON IT. ANY SUGGESTIONS OR FEEDBACK WOULD BE APPRECIATED. CHANGED SPARK PLUGS AND WIRES.

Mine did the same thing and found out it was a bad spark plug. Replaced the sparks plugs twice now on #1 with 87,000 miles on my 2008. First time they said it was a cracked spark plug. The second time the spark plug was fouled with oil deposits. Also check the wires once more and see none of them came off.
