Low Gas Mileage

For whatever reason, I've started getting abnormally low gas mileage. Can you guys make some suggestions on components that can cause this effect when they need replaced? I dropped from like 14-15mph to 10mph. thanks

That's right. A few weeks ago I had a friend's father tell me it sounded like my Cat was bad. I bet that might be the problem. I think my sensors should be okay, but I might check into that also. Any other suggestions guys? Thanks!!

has your idle increased or decreased??? decrease would suggest a clogged cat . increase would suggest leaking intake gaskets . i just got done replacing ALL the gaskets in my motor as i had a high idle and leaking oil all over . easy way to cheak the gaskets is to spray some starter fluid around the gaskets . if your idle increases then you got a bad gasket . ( and yes my gas mileage sucked big time )
