nissan armada catalyst converter

[indresda]

I need help....I reset my Engine light because my Armada failed the smog check...error P0420. After a few days the engine light came back on. Had it checked and the OBDC reported the same error P0420.

Now what do i do? I need this fix ASAP. Can i do it myself? and if i buy should i upgrade the my headers and have the catalyst converter weld on?

thanks in advance.

Based on the other threads scr38 suggested you have a bad driver side cat. So yes u need to replace the cat. If u are going with headers u still need a cat. So a b pipe with cat attached. There is a titantalk member nightowl, he has a Cajun b pipe with cat for under 200. U can install it yourself if u are "incline" to. Some say its about 8-10 hrs process.

Maybe some others will chime in. Scr38 has more knowledge on this matter then I do.

Hi scr38, I'm really confused on what i should do...I really can you use your input, please.

Can i do it myself? and if i buy should i upgrade the my headers and have the catalyst converter weld on?

well since nobody want to help me to understand...I figure, I'll do it myself! Called in and waiting for the part to get to my house.

Can someone explain how do i go around this process -

- Before installing a new heated oxygen sensor, clean and lube the exhaust tube threads using Tool.

Tool number
A : — (J-43897-18)
B : — (J-43897-12)

Thanks

I know I'm coming in on this pretty late, just happened across it. I'm surprised nobody else other than ntrddragn has chimed in. Where is everybody?

Me, I'd go for it! Wish I could offer you some insight as having actually done it myself. These kind of jobs though I would not shy away from. I don't know that you need any special tools more than just the replacement parts. It'd probably help if you have pneumatic tools but if you don't it's probably still just as doable.

If you haven't finished the job already, keep us posted. If you have, how'd it go? Let us know.., if no one else is interested, I am. Drop us a line!

I think there are a couple how to threads over titantalk.
Richard was saying someone he knows uses clamps rather than welding so if there is a failure with a section then much easier to fix... i'm somewhat curious about it.
i'm not too sure if you need/needed new b pipes... heard good things about the cajun ones. pops was saying hE might ask local shop to custom fab some b pipes.
i'm with turtle on tool issues... air tools would prolly be helpful.

yeah, webturtle he did buy the headers and replaced them. last i heard was he had a stripped bolt and need to re-thread it. And he ask about torque spec so i assume he got it squared away.
