I have a 2003 Impala. The check engine light came on and I had the codes read at Advanced Auto. Seems the it is running too rich. I put some fuel system cleaner (Sea Foam) and wanted to clear the codes. I was told they can nolong do it because of pending litigation. I remember clearing codes before by somehow using the radio. Any ideas?

 

unhook the battery for about 30 seconds....it may be you still have a problem tho
