4030 code

[yetijohn]

Hi. Got the 4030 code showing and am wondering what solved it for other (if any) people. Car runs fine. I know it could be O2 sensors or the Cat (hope not). So any info would be greatly appreciated. Thanks

Cheers. I've had a look around online and have seen a few suggestions. Just thought I'd ask directly on here in case there was one common part that has solved the problem.

Have you changed anything recently?

Had Oil/filter & plugs fairly recently. Could be a coincidence ? Like I say the car runs sweet its just bugging me.
