mass airflow and o2 problem

where is the maf on a 92 camaro 3.1 v6 , and how do you tell if the o2 sensor is bad? because i have no idle , i have to drive with two feet just to keep it running. also its burning gas like a v8.

If it has a MAF sensor it will be located between the throttle body and the air cleaner. Some FI cars in the early 90's were speed density systems and did not use MAF sensors.
If the O2 sensor is bad it should have a trouble code stored. Is the "Check Engine" light on?
