Let's stick with the mounts and idle speed before getting into the "car doesn't crank every now and then"...that is where I was going with the CEL. Think you have enoguh to track down for now....and the hard starts could just be a sign of the wanting a tune up.

 

My apologies for the delay in reporting back, I am in the process of moving. The CEL does not illuminate when the key is turned to P 2.
