Need help Passing smog
Recently Acquired a 1983 280zx and it had been sitting for a while. I took it to get smog checked and it was pretty bad. I got a new catalytic converter, and even had somebody repair the EGR system, and now only the NO level is just a little too high. Any suggestions would be greatly appreciated.

Welcome to ZDriver!
How long is "a while" ? Does it still have old gas in it?
What was "pretty bad" ? Details...
What did they do to "repair" the egr system? Details...
How much is "a little too high" ? Details... scan the emissions readings please.

Thanks for the responses.
this is the old smog check.
That is the newest one.
Quite honestly i'm not sure how long it was sitting for. I put a little gas in it, but there is probably some of the older gas in the tank.
As far as the EGR system, the mechanic told me it was not working, and that he had repaired the system.

- Get rid of the old gas.
- Check timing.
- Check / read / replace spark plugs (NGK's only!).
- Check / replace spark plug wires, cap, rotor.
- Check / change oil.
All the stuff you SHOULD do before taking a newly acquired car to emissions.
