Default Smog Test

Hello,

I have a 1993 Ford Ranger - 2.3 liter - 4 cylinder

I took the smog test today and failed. They said that my MEAS reading was too high. The highest reading aloud is 69 and my truck read at 499. That there was too much unused to gas coming out of the tail pipe.

Does anyone know anything about what this is and a possible fix?

Thank you in advanced!

If you don't have that sensor hooked up the computer will think the engine is cold causing a rich condition.
