OT:Emissions questions regarding the readings on a particular car

[1974ChevyC10]

ok on my taurus which i will be driving when i start my truck swap project here soon.i now have some questions regarding its emissions readings.it will be registed at my dad's po box in northern arizona where they dont require emissions so i wont have to spend a bunch of money on the car(more money for the truck-woohoo).basically i want to know what could be the cause of the following readings to be so high.here goes the results

equipment or pressure inspections
gas cap-pass
evap components-the paper says there inaccessible-wth does that mean-the inspector is blind and cant see but next to that it says ok-im stumped on this one.

emissions inspections results
hydrocarbons(hc) in grams/mile-vehicle reading 2.05 applicable standard 1.00-car failed there
carbon monoxide(co) in grams/mile-vehicle reading 25.09 applicable standard 12.00-car failed there
oxides of nitrogen(nox) in grams/mile-vehicle reading 2.88 applicable standard 2.50-car failed there

im not going to run it through emissions for now as i said b/c it would cost more money than im willing to spend right now-it would cost me in total like 5 or 6 hundred dollars to get it to pass the emissions test here.please give me some idea of what components and/or systems are at fault so i can at least repair the major items.the car runs now as it is but it doesnt run properly so i want it to at least run better so it dont give me fits for the time i have to drive it.thanks in advance guys.

just before i go to any emmissions inspection i tune the car up new plugs wire cap rotors air and fuel filters and ive never failed yet ya sure its just not out of tune? youre really not that bad on those tests

im not sure exactly what is wrong with this car thats why i was asking for opinions on the subject.im sure a tune up wouldnt hurt it but for readings that high i suspect it needs more than a tune up.

It's fuel injected and the computer is controlling everything. It looks like you have a handful of crap to guess at what's wrong. I wouldn't have any idea where to start though. Unless you have access to a diagoistics computer, you will end up spending a ton of money trying to replace what it could be. This is why I hate the computer controlled vehicles.

I had a 1990 Taurus GL, had 181,000 on the clock, ran like new, just traded it for a new Taurus.

You got a decent car there. I hate to say this, but you need to pull some codes. Make sure your timing is ok before you go. Only make timing adjustments with the gray connector at the dist. unplugged, It's called a SPOUT connector. Run some fuel injector cleaner through. Like everyone else says, put some motorcraft plats (correct gap) and a cap and rotor set on it.

The emissions people are blind at the inspection station by the scottsdale airpark.

thanks for the tips guy.elwood it was tested at the emissions station in apache junction or the one on greenfield north of the brown rd in east mesa.the ex had it tested but she has another car so she dont drive but im going to drive it while my trucks are down.looks like its time for ol dad to bust out his ford code reader he got one when he had his 87 mudstain oops i mean mustang.the taurus isnt a bad little car actually but i would like to get this problem with it resolved so i can sell without hassle after my truck is done.
