I'm discovering, fix one, find another like .I'll admit, I ran it to long with bad O2's. They were bad when I got it but the previous owner blocked the CEL so I couldn't see the light .

Anyway, I replaced sensors, got random codes, cleared them .Then about 100 miles in, these 2 codes have come up. If I have a bad CAT would that cause the slow response from the O2? Open for ANY and ALL suggestions, ideas and advice!

Thanks in advance!

 

0420 cat compromised, install an o2 extender youll be fine. It could eliminate your o2 code too.
cheers

 

What is an O2 extender and where might I find one of those?????

 

 

Ok great. Thanks a lot .How long of one do I need? I look on eBay and they seem to range from an inch to a mile .Lol

 

 

I may be crazy here but if your cat is FUBAR just replace it. 100 bucks on eBay. I had a new magnaflow system put on my daughters truck 2 years ago. The passenger side cat busted some internals loose a month ago. Just replaced it .cheap as hell. I gotta talk to her about the size of boulders she is allowed to go over.

 

And that's exactly what I'm trying to figure out. Is the cat FUBAR? is that what is causing the codes or is it something else?

And yeah, you may need to have a bit of a chat with her lol .I'm in southeast Missouri and we have rocks here a d I've never came close to busting anything on one .lok

 

Bang your muffler if you hear anything rattling around inside it “could” be the internal parts of your cats have blown out.

 

Ok, I'll try that for sure tomorrow.
