DTSC light is on. Idles high when hitting slippery spot. Codes received are P1173-68 and P0507-00. Any ideas what this could be?

These codes are fairly vague and caused by several electronic components. It could range from a front o2 sensor to a clogged air filter to trouble with the fuel system. I would take it to a reputable mechanic to have him run diagnostics to narrow the problem down.
