Hi, just thought i'd ask...

Fitted a De-Cat a few weeks ago on a mates FRS, it's running fine but about 3 weeks ago the management light came on, checked the DTC and it said the Cat was faulty, obviously it's not there so I cleared DTC's, and it was ok, now the light has come on again...

I have read about using a MIL lead, but never heard of them being used on an FRS.
