HAVE CHANGED OUT BOTH map & tmap sensors after P0107 code is identified. Also DSC light comes on when this code occures. Could it be possible that the O2 sensor might be causing the problem code? also have had the DSC light come on by itself for no apparant reason. Any help or possible soloutions would be appreciated. 350 miles to dealer in Salt Lake. 2005 S with JCW.

If these do not help, start looking for vacuum leaks. Do a smoke test, or hold a length of hose up to your ear and pass the other end around the engine compartment. Listen for a hissing sound.
