I get the feeling I will be in the vast minority being concerned with a P0420.
12/25/21 code appeared, reset
We can inspect current month, and next two, in PA. So since the car had October 2022 stickers, waited until August 2022, inspected the car, got October 2023 stickers.
Sure enough, P0420 again September 2023! Lucky we inspected already.
Why, well, with this GM if the codes erased, its I/M will be ready in around 100 miles, EXCEPT FOR EVAP, which takes 700-1100 miles.
Since 9/22, the car has never gotten itself into a I/M ready before the code came back.
My brother and family came to town 4/28 for the weekend, and we drove all around, and the tank was much lower than we normally let it get.
Last week, I found the car was I/M yes to all.
Went to indie garage, asked for an inspection, and of course, they wanted to know why on May 19, when it's good through October.
I explained the P0420 blah blah blah. They said ok. So if it costs $42 for 12 mos, I figure I am throwing away 5 months, but buying time to deal with the issue (a friend paid the dealer $1800 for same code, same car, in 2019).
When picking up the car, to my surprise, they put 7/24 stickers on it. They do have the prerogative to do so, because today, May, Jun, Jul stickers can be issued in May. So we have 13 1/2 months to deal with the issue.
Car being a 2011, I told them Walker cat if it needs replacement, being ~ $300. We are allowed to install Fed certified cats on Calif cars in PA. Not true in CA, ME, CO, and NY.
I know my cousin also has P0420 on his 2004 M5, and he resets the codes, drives until ready, and parks until emissions testing, in MA.
Emissions is a pita and I feel it often spells the end of a vehicle in states with testing.
Do you have any P0420 or P0430 stories to tell, and how you dealt or deal with them? They lower our overall quality of life
