Default SES light comes on periodically

I hope this is the right forum but I have a problem. Ever since I got my t/a back from vette doctors with the qtps headers and catted ypipe and linelock and fanswitch installed the Service Engine Soon light comes on once in a while and then goes away it has been happening for about 2weeks now. I think it only comes on when I use the fan switch but not really sure. Any info would be greatly appreciated.
