Hi,

I have a 90 300zx N/A and I'm trying to get it to pass emissions legitimately. It failed the first try, so I changed the catalytic converters, then took it again. The smog guy said that everything was good, except that my EGR valve or pipes might be clogged. Since it's a lot of work to get to it, I'm wondering if it's just good to delete it? If I do delete it, it won't pass inspection, but will it pass emissions? Also, if anyone has done the EGR delete or replacement with the engine in, what was a good method to go about it? Thanks.

 

To clarify... so did your car pass or fail the second time?

??? Still not sure if it passed. California smog tests are very strict, all other states, it just depends on the tech.

Did you see this? First Google result...

My Z didn't pass. The smog guy said that the lines of the EGR are clogged or the EGR valve isn't opening. I was just curious to see, since I might have to replace the EGR, if it will pass emissions without it. I know that it won't pass inspection, but since it's well hidden, the smog guy might over look it if the emissions are all good. I saw that post, but didn't really answer my question if the car would pass the emission part without it. Thanks
