Hard start, cold start problem,rough idle...now Idle Switch/MAF code

Just for curiosity's sake:
On the V8, the engine speed sensor has a history of failing with age. It
sits under the driver side exhaust manifold, supposedly protected by a heat
shield. When it starts to fail, the car will not restart when hot. Will
start cold and run OK cold/hot, but shut it off and try to restart a few
minutes later and there is no go. I'm guessing the ECU needs signal from
the sensor to let the ignition spark.
Has anyone ever found an engine speed sensor go bad on an I-5 engine?
Could that device cause poor idling on an I-5, but not necessarily no start?
