Default Running rich?

I have a 96 civic ex sedan that is bone stock. I think it is running rich since every time i drive it, stand outside of it when it's one, etc. i can smell gas. Especially if i were to rev the egine a lil bit. I am guessing it is because I have no muffler since the last owner "sawed it off". -.-

anyway i can get it back to normal. And i know i sound like a nub but i don't want to take it to a shop and end up paying a **** load of money for something i could do by myself. Plus I want to know what are some of the possibilities also.

Are both O2 sensors intact and working? Are you seeing black smoke? Any CELs?

If you are smelling gas you may have a leak some where check all your lines under the car maybe the fool that "sawed off" the exhaust also nicked a gas line also look for black smoke coming from your exhaust as that indicates unburnt gas also you could monitor your gas milage and see how good/bad it is good luck

This may sound overly stupid and obvious...but are you smelling gas when the car is cold/warming up?
If so, that's pretty normal because it runs a little rich at first to warm up.
If not that, then I agree with Jdubbs in that maybe the dumbass owner hit a gas line.

Working o2(s)??? - And you can buy a cheap quiet muffler (or loud if you prefer) - and have a shop put it on for like 20-30 bucks...

O2 snsors are working and ima check to see if the gas line is still intact. But it warms up fine and all, just smelling gas when i drive it after it warms up like in the middle of the day. I live in sw florida so it doesnt really get cold here.
