SLP header fault code
I'm posting for a friend who had the SLP headers installed on a 2002 LS1 and had the ole check engine code show up right away. After checking with SLP (the code indicated O2 sensors not switching correctly) a pair of seems were ordered and installed and now the same code is back?
Any Ideas?
