RPM drop

This car has the MAF sensor (of a sort) instead of CIS, correct?  If that is 
the case, more than likely, that sensor is worn out...  It has a brass arm 
that slides along a track to tell the ECM where the air flow is...  If it has 
this type, with many miles the are apt to wear through...  If it does not have 
this type of sensor, ignore this post...  :-)
