Default 95 olds cutlass supreme runs rough at 55mph @ 2000 rpm

My 95 olds cutlass supreme runs fine etc until I get up to 50-60 mph at 2000 rpm when it will run rough, like its not getting enough fuel or spark.
I changed out the plugs and wires to no avail.
Is there some kind of overdrive sensor??
Any suggestions?
