I've replaced everything that pulled a code. Now all that happens is rough idle jerks when shifts. No codes now, Ive replaced wheel and sensors, steering wheel sensor, and so on. Does anyone know what's nect. I've throwed so much money at my old 07 IT 5.3 crew cab. Pulling no codes, but service stabilatrack, and traction control lights still come on and rough idle. Still jerks when shifting. Thanks for any help here. Joe

 

You need to bypass the active fuel management system. Also, change plugs and wires if you haven't recently.

Those steps worked for me when I had that issue.
