Driving home tonight and POOF!! P0420 now remember I got the car back 1 week ago Monday from replacing the other one for P0430........ What a PITA!! Gonna call Kachina tomorrow morning and see if I am going to have to take it in for them to read the code. I sure hope not cause its an hour there and and hour back. What really sucks is that I was going to have my emissions check done Friday.

PGA2B, don't hesitate to send me a private message if you would like me to contact your dealer on your behalf at any point. I'm always happy to follow up with them regarding your concerns!

Best,

Katie

Thanks Katie but I have a very good relationship with Dan Boardman at Kachina. So no issues there.

i have onstar and they can read a codde for you--also AAMCO does it for free if thheyre nearby
I have HP Tuners Pro so I pull my own codes. They just need to document the code for Emissions Warranty purposes to get paid by GM for the work.

Yea, I,m still waiting for mine. Had same P0420 and when I went in the Tech made an issue
about my Spectre Intake. My service advisor said no problem. I have been waiting a week now, maybe they will
get new manifold next week. PGA2B, have you ever considered poly-urethane differential bushing? Found a place that sells
them and might change mine out.

Mine got replaced under warranty back last July. If I have the car next time it needs to be replaced I will go that route. There is also a company making Upper and Lower front control arm bushings and Upper and Lower rears for ours and should be ready in late March or early April. Mine are squeeking like a hoopty.

My manifold is on order and will be here 1-2 weeks. Has to come direct from GM but it is in stock.

If your diff bushing is bad you will feel vibration in the driveshaft that will cause you to feel it in your seat. As for Control arms you will hear it squeek going over bumps and when you stop.

PGA2B, Just curious if you got your manifold yet.
I have been waiting one month now. The dealer
said they had to order direct from the manufacturer.
I think 4 weeks is a little bit long to wait on a part that
is under federal emissions warranty.

I haven't yet. But to be honest I haven't checked on it either.
