Check your EGR valve and EGR modulator. My modulator went kaput and I was failing with 1360ppm (max 1200). Swapped in a used one (25 bucks) and it shot down to 750.

no idea how to do that, ill prob just get the egr and the modulator looked at by my neighbor, who is a mechanic. i have no idea where the egr is

Excess ignition advance will also raise the levels. I would check static timing to see if its in specs. You can always drop it to no advance to lower emissions and then put it back after you pass. Putting in 20% E85 will also help. But, I agree with fixing the EGR. Its main purpose in life is to lower combustion temperatures and reduce NOx.

okay, so been doin some thinkin... i am using 3VZE spark plugs in a 22RE.... i know when it burns cleaner, the NOS levels rise. so im gonna try putting regular 22RE spark plugs in it and run it for about an hour on the freeway then immediately take it to the smog place, where i have a free retest. am i thinking in the right direction, or am i WAY off?

Find a shop that does retesting and that works with the state and they can set you up with the right paper work for state accidence. You pay first $100 they state pay up to $500. Thats only if you whore required to go to a smog only station. In the first place. It worked for me.

yeah coming to think of it man its the egr and try out the timing cause on mine (thank god we dont do emissions here) is at about 40 btdc so yeah id try the egr thingy then the timing then go again
the egr is right at the tip of the wrench that pipe there and the cly looking thing with the vac line on it your should be the same the pipes look like water pipes on a old building just so you know

ok, took my truck to the mechanic my parents use today, and he started trying to play me. he told me the EGR is bad, and theres no way to clean it. that once you take it off, you cannot put it back on. and its about a 500 dollar job. (i know is BS). then he told me if i need it smogged, give him 250 and he'll pass it. is it worth it to pay the 250, or should i get a 2nd opinion on the EGR? i just called my old mechanic up in vegas, and told him, he said its prob not the egr thats clogged, its probably the line going from the egr to the exhaust, or something. what should i do?

Technically he is right. In the state of California a mechanic can not knowingly install defective smog equipment. If he takes it off, tests it and its bad he cann't put it back on. $500 is about right for parts and labor if he uses an new EGR.
Since he offered to pass you obviously he is not playing by the book. Report his happy @ss to the state. They take that kind of thing fairly seriously around here. It only takes a few complaints and he will lose his license.
The EGR is a little bit of a pain to pull of, but it can be done with a very minimul amount of wrenching ability. Pull it off and clean it out with some carb cleaner or seafoam.
