How do you get rid of carbon build up. My car started having problems like it would not shift gears or couldn't go past 60. A code came up to change EGR value which was down but now misfire code still appears.

GM make a great top end carbon cleaner, techrolean or fuel injection cleaner you add into the gas tank will help. If the EGR system is clogged up nothing short of removing the valve and cleaning passages is needed.
