I recently had to replace the cat on my car following a theft, and I opted to got for a sports cat since it was cheaper than an OEM part (Honda wanted 2k!) And while the car runs absolutely fine with no apparent problems, the EML light keeps coming on. I'm assuming it has something to do with the non OEM cat, but any ideas you may have would be appreciated.
Car is a 2002 Honda HR-V 1.6 (103 4x4) if that helps.
Thanks
David.
