Failed SMOG again in CA...High NOX count....

[worangejuice]

failed SMOG in CA. 180,000 miles, original everything i think, new spark plugs, stock intake, custom 2.5 piping fart can exhaust, seafoamed 2 years ago..........My NOXX readings are off the charts... Im gonna look at EGR and seafoam it, besides tune-up (distributor, wires,cap, CAT(hope not))can anybody suggest anything else???

*UPDATE*

So my readings are significantly better. SMOG tech said its my BPT Valve. Because its not recirculating emissions back into EGR.
Vaccuum tested BPT also and no pressure at all. I watched him test, he was pretty cool. He said if it was a bad CAT then all the readings would be fairly high across board (all would be effected)
I guess id need to clean the intake runners as well?
I had car running hot also (drove around for hours)
I am down to half a tank and that "guaranteed pass" bottle stated to run tank empty and then put gas in then SMOG test. But Ive been driving all over town and just need to SMOG to sell to a buyer like 4 days ago........F'ng A MAN
