How do I lower my HC to pass emmissions?

I have a 89 Olds Cutlass Ciera that passed everything but NOx at first, 2.75, should be 2, then after I ran fuel injector cleaner through it and then later octane boost, my mechanic happened to find a broken fuse end in my EGR valve and said that could be the reason why it wasn't passing NOx... he couldn't do the test because his machine was down... another guy checked the EGR valve and said it was faulty and that someone must have put the fuse in to bypass it, but I know my mech wouldn't do that... he wanted a high amount(over 500) to change it... so I took it to my wife's cousin's shop where he works, and he said he was pretty sure he could get it to pass for me... NOW the NOx is .09 but the HC is about 3.5 when it should be lower than 0.8, which it was earlier... I remembered I hadn't changed spark plugs or wires in about two years... so if I go get them changed, the HC should pass then right??How do I lower my HC to pass emmissions?
never mind the additives and the cat, do a full tune up and the hcs should drop.How do I lower my HC to pass emmissions?
change the fuel mixture.. that is three gallon of gas to two quarts of menthenol.. and it will pass...How do I lower my HC to pass emmissions?
Also change your cataletic converter. a new converter will give you great emissions results.
