smog fail

What is your question?

My car failed smog for the 15mph max is 64 I had 66. I failed by 2 points. 1) Will it help to drive your car for about 1/2 hour before. 2) but before doing that, does it help to put in fuel injection fluid when 1/4 tank of gas run car hard then take it in for smog, then put in the gas? 3) I did not do my spark plugs for 3 years. Will it help to get those changed before my retake on my smog. 4) Does it help to drive the car in the rain? Thank you
