My clothes smell like gas

[Just me]

I got this problem guys. Every time I come home from cruising, my roomate says my clothes smells like gas. I don't notice any gas smell from inside the car when the windows are up, but when their down I do notice an unburned fuel smell at idle. I expect this considering my mods. What I've noticed lately when I drive the car a good 50 miles or so and shut down, if I pop the hood I can smell gas in the engine bay. First thing I did was check for leaky injectors but their fine. If I stick my head in there and sniff around(doesn't sound good lol), I can smell the gas coming from my conical. That seems to be the only place. Well I checked my plugs and their all burning perfect. I've done every test(compression, leakdown, etc.), everything is fine. I get the check engine light flash on for a couple of seconds when I accelerate quarter throttle. I've checked my TPS and EGR, and bought new o2 sensors begining of 99 but have been through alot of testing and tuning since then. my car runs rough for about five minutes on a cold start. How do I clean my o2's? Anyway, can anyone help? Sorry for the 2 part novel.
Thanks. Here are my specs:
