05 STS P0430 (bank 2 cat efficiency)

Or use the Tech 2 that I have...

If only you had a factory scan tool currently in your possession...

Light is still out. I need to use more WOT on this tank to get some heat into the cats, which I would presume enhances whatever cleaning capability the chemical provides.

Looking back in the thread, it's actually been a month (Jan 23) since I reset the code, even though the light has been on and off multiple times. Self-healing cats, sure.

Still out.

I guess I can stop updating daily but still out. The next test of significance will be the next time I get gas. If the light doesn't come on shortly after I leave the station, then I'd argue there is some improvement.

Just ran the tank with the additive down to about a gallon left again. Filled up, light still out. Feeling slightly optimistic about this. I would happily settle for a light every few months that I can just reset and ignore for another few months, or perhaps the occasional bottle of stuff (as long as it is not every tank). If this reduced it to that, I'm kind of good with it forever, unless something happens like the cat clogs or disintegrates.

Light still out. I even remote started it once or twice and still nothing.

I always jinx it. Gassed up last night. Light came on after a mile or two of driving this morning. Haven't scanned but I think I know what it will be...

I may just do nothing and see if it goes out again since that is a thing now.

Light out this morning. Seems to go off after about 3 days.

So...German?

Came back on yesterday while running errands.

I guess I'll try another bottle of that stuff...
