Her or her GX?But what happened with bamagirl?
Bought one of these back in march, no problems yet!Anyone recommend O2 sensors that are decently priced? Also what antifoulers yall using.
Replace O2 sensors in pairs….that what I did with denso ones.Has anyone tried Oxicat (or something like it)? Seems like this stuff works some times and should be the first step but nobody here mentioned it. Anyone with any experience?
Also, many replace one O2 sensor but advice on the web says do both downstream ones at the same time. Advice?
Also, concerning the "antifoulers". I have never heard them called that but I had to use one on an engine swap once. It pulls the o2 sensor out of the main exhaust stream a bit and "lowers" the reading. It worked perfect for my car (2003 MR2). It is not trying to defeat the cat but to adjust it a bit. From what I read, on older cars this can help. I think only use it on the downstream one, though.
I had the same issues with P0420/0430. These codes are most definitely catalytic converters. Each 02 sensor has its own sets of codes. I replaced all 4 02 sensors anyways, didn't have any affect on the codes. I purchased two of these for the rear 02 sensors- O2 Simulator Mini Cat Cel Fix stainless steel Rear O2 sensor simulator. - http://www.bigdaddiesgarage.com/mini-cat-cel-fix.html. They are basically a mini-cat for the rear 02 sensors. Codes have been cleared and haven't come back and I passed the ECU check for GA emissions. We also have a visual inspection, but in my experience, no one has every looked at anything other than plugging in the ECU and checking the gas cap. I've got DT LT headers on hand and plan to replace the factory manifolds/cats with LT headers. I've only found one shop to take on the job and they quoted me 8hrs @190/hr. I've found a friend/shadetree mechanic to do it for half that.Also what antifoulers yall using.

Lost my login info when I cleared my browser history and didn't set up 2FA. Anyways, the mini cats worked for about a few weeks, enough for me to pass emissions, but 420/430 came back.I had the same issues with P0420/0430.
