Default Some Problems Help.

I am having a problem with my car missing at idle. When i start the car it idles ok and then in about 2-3 minutes it will smoke and after about 20 minutes it wont smoke anymore. I installed headers and deleted the cats, air and egr, but did not get a tune for the long tubes, will this cause my car to run liked that or run rich. I installed a new opti, plugs, wires, fuel filter, and ory pipe. So i dont know why it is poping at idle. It will also not idle by itself without me giving some gas. Dont know if i need a tune or what but i had the idileing problem before the headers but not the miss. Sorry for all the questions Thanks in advance.

Are you plugs wires touching your headers and arching? If you installed L/T's and removed your O2's this may cause your car to run rich. And maybe your fuel pump is slowly pooping out on you.
