I'm Back! (P0421 CEL Code)

[7milesout]

My experience was not exactly the same. The first one I paid $50 for (seems like it was from some jokers called Big Daddies) was supposed to be a minicat too. It had a small hole, like the top one. It didn't work at all. The 2nd one I bought was a $9.34 from Walmart. Also supposed to be a minicat. It had a bigger hole with a grid, just like the one pictured at the bottom. It worked like a charm.

As for the P013C ... I ain't got the foggiest. You done gochew an OBD-II Bluetoof ELM 327 connector and phone app right? The connector is usually <$15 and phone apps that work with it are FREE. Ain't no reason in life not to have these. These work for my whole fleet of cars (well, not my 72 Plymouth Scamp), some more limited than others. But I can check and clear codes on all my vehicles with the connector and phone app. If you're not able to see your codes, I'd Amazon an ELM 327 today. Tellem Charlie sent ya!

Ok... I just got the car scanned at O'Reily's and now it's saying that the O2 sensor isn't reading properly (which makes sense with the spacer installed) Should I try the mini-cat O2 sensor spacer or would I run into the same exact issue?
