1997 Ford Taurus rough idle at start up and raw gas smell I

My 97 Ford Taurus GL 3.0 occasionally at startup (either cold or warm) will rough idle and sometimes stall, and when it does that ill have to give some gas for it to idle normally, and from time to time when this does happen ill start to smell gas inside the cabin but cannot smell it outside of it, ive checked for leaks, the spark pug wires and yet nothing im planning on pulling the spark plugs later today after I replace the water pump. This is baffling me to no end, also the car when running runs perfectly no signs of pistons not firing, and the oil looks and smells normal. Ive done all the repair work myself with the help of family and friends. Ive recently replaced the VSS sensor, belt assemble bearings, new tensioner, struts, wheel bearings, recent tuneup, lights, and interior repair which in my opinion would have nothing to do with this problem. The car has always had this problem since I got it but with the colder weather, and running it more often for my new job has made it worse but not quite at the point where I cannot run it without seeing the problem. Open to any suggestions. Thanks in advance, Ryan
