I installed my groundfusion grounding kit saturday night and this morning I found that I'm now throwing a CEL. Yesterday's drive to/from work had no CEL's at all. I have a MMW header/spipe, but that has never given me a CEL yet. I'm taking it to get the code scanned when I got out of school, but does anyone have any idea as to what it could be?

 

alrighty, went and got the codes @ autozone (along with clearing them out). PO441 and PO455
