Q: Is it possible to pass a California Smog test with a bad EGR valve? on 1994 Volvo 960

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
I got this car and got it smogged on Saturday, but on Sunday afternoon my check engine light came on. I took it to a shop and they ran a diagnostic and told me I had a bad EGR system. However with a bit of research it doesn't seem possible to pass smog with a bad EGR valve. Maybe it's just dirty or maybe it's something else? It starts up a little rough but idles and drives well, but I did notice a lack of power at low speeds on a cold engine on Monday.

may have passed yesterday and the egr failed today. anything can happen.

just think, if you had your smog test tomorrow, it would have failed.
if you dont believe them, get a second opinion.
