Question about 2001 Oldsmobile Aurora
If this is the 4.0L engine it is very common to have the Air Intake Plenum gasket crack. About a $30.00 part and 2 hours labor.
First, see if you have any codes. For the situation I describe about you should see P0171/P0174.
The other sensors could also be the issue. Most ODB-II scanners will allow you to read "live data". This will go a long way in telling you where the problem is.
