92 Camry Gas Smell in Cabin

I have just changed the oil / plugs in my 92 Camry with a 3.0l V6 and now I am getting a slight gas odour when I am idling at a stop. This is new since changing the plugs etc. and I am wondering if I have done something wrong or what may be causing it?

The three plugs at the back of the motor were quite difficult to change and I am wondering if I may have knocked something loose....

Any ideas?

You might want to check and see if you've damaged any fuel lines or anything against the firewall...other than that, I really don't know what all could cause the gas smell you've got. I'd say just check around the area that you were working when you changed the plugs and see if you can see anything disconnected, or dripping. Best of luck, and if you need any further help, let me know.
