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

[Derek Pulvino]

Ok, so I ran the fault codes yesterday and got two that seem to make sense.  
First was for the idle switch...second for the MAF sensor.

The idle switch makes sense, but I do still wonder why it seems to only 
effect the idling upon restarting a warm car and not when the car is started 
cold...even after the cold started car has warmed up, and also why this 
problem only creeps up when the weather is warm.  I checked the open/closed 
continuity of the switch after getting the code and it's fine...maybe need 
to do the check on a warm car as that's when the problem arises.

On the MAF, problems there do make seem cogent with the odd stumbling I've 
been getting, but I also wonder if an idle switch problem "confused" the 
system into throwing this (MAF) code.

Ran the output tests this morning...everthing cycles just as it's supposed 
to, including the ISV.

Any input of similar experiences from anybody?  Oh, and my car has started 
to require more cranking on cold starts now.
