So....
My 07 Charger R/T shot a P0420 code at me 2 months ago. It has 260,000 miles on it and I've taken obsessive levels of care with it since new. At the time I bought it Chrysler was offering a life time bumper to bumper warranty which I happily purchased.
This car has given so few issues over the past 15 years until now.
For those that don't know, P0420 means the catalytic converter isn't performing to spec.
I took it to the stealership figuring it would be covered by the warranty....WRONG!!!! They say exhaust components aren't covered. To me it's emissions, not exhaust. They give me a quote of over $5000 to replace both cats and O2 sensors....f**k!!
I live in PRNY ( peoples republic of NY) and our cars have to meet California emissions (CARB) so the cats are twice the cost of the rest of the country. Double f**k!!!
So....I hop on the ol' interwebs to see what options I have. A lot of folks have had success putting spacers in the down stream O2 sensors to trick the PCM. So I put spacers in the down stream sensors, clear codes and go for a drive cycle......50 miles later...Bing!!! P0420.....F**k yet again!!.
OK, I look at the O2 sensor voltages and they look fine to me but maybe there's an exhaust leak or the downstream sensors are bad. 2 new downstream sensors and 50 miles later...Bing!! P0420. How many times can I say F**k????
Hail Mary time and I go for the bank 1 upstream O2 sensor.
. DAMN! That thing is a bit*h to get to. After much cursing and scraped up arms I get the old one out. Houston, I think I found the problem.
I'll let you know in 50 miles...
