95 fuel system question

I just purchased a 95 aurora, it has high miles but I dont need it right now and have time to work on it, I just put new plugs in it, it doesnt miss but it does idle rough, I have also noticed that when I first start it I can smell gas and when I rev it I can also smell it, any suggestions on where to look, I have seen a lot about fpr's will they show up on and obd scan? Anyway, I know a lot of this has probably been covered, but my searches arent really getting me what I would like to find. THANKS!!!

All 95's through 97's are being recalled due to fuel rail leaks. Suggest you NOT start the car until you can determine if the fuel rail is leaking. If it is, find an Olds/Caddy/other GM dealer and have the car towed in - you don't want a fire!
