hello everyone this will be my 2nd post here today.
I have a post in the law enforcement/smog sec but
in more detail over there, but don't know how long
to get responses over there.
So to my point on my 08 gsr it seems three smog
shop I've been to are misinterpreting my vehicle
emissions control sticker saying that my car needs
2 cats when i know our cars only require one.
Here's the #s HO2S/TWC/HO2S/TWC/SFI
I went to the dealer gave my VIN #s and copied
the exhaust and gave me the diagram which shows
one cat.
now how do i convince the next shop or the last
shop i went to that they were wrong. thanks
