If you put a new cat on it, you're guaranteed to fail at least two tests after that, unless you go put a couple hundred highway miles on it first. The cat needs some time to break in at first, that was one reason why I failed so many times, so says my smog guy.
My truck also put out too much raw fuel, more than 3 times, almost 4 times the allowed amount. Rebuilt the carb and wired the fuel cutoff solenoid properly. The PO hacked the wiring on that part for some reason.
I passed with more motor work than you say you have. But a while back you said you had a lot more than me done, so I don't know. If you just have a cam, header and intake you should pass just fine.
Don't try any of the "Pass smog" or "Help-U-Pass" crap, it sucks. Especially on a fresh motor.
If you can find a cool enough guy at a Test Only place, have him run the truck in 3rd gear for the 25 MPH test, because that is where most Toyotas fail. They do worse at high RPMs, so running in 3rd reduces the RPM and the emissions output.
Also if you can, stick some ice (in a bag) in your intake before going into the station. It helps a good deal. You still have the stock intake right? Just with a K&N filter in it?
Also, we did all this with my truck, and still failed, but were close. We then ran it with no filter whatsoever, and ice around the edges and passed with flying colors. This was when I had a Fram filter, I switched to a K&N afterwards.
i put a brand new cat on my mazda, and did the test literally right afterwards, like within 3 minutes, pulled it off the rack and smogged it, ran it at 4500rpm for about a minute or two to burn the crap off inside it, and i passed with flying colors, better than brand new actually.
also being "21 degrees" off is probably advanced, when i took my truck in it was at 21 degrees advance and is only suppose to be at 6 degrees. and it was running top notch.
the easiest way to be certain to pass emissions is thing, gap your plugs a decent amount (not too far because then you will blow out the spark with compression) and put like a pint of airplane fuel in your tank along with about a 1/4 of gas, this will make it run awesome, i have seen an accord (my old 1980 hatchback) blowing smoke like crazy and i did those two things and it passed and nobody knew how lol. anyway good luck. OH and in california your idle can be legally 1100rpm at idle and still pass idle test so crank that biotch up to 1100 for idle, we did on my mazda.. and heres my reults...
