I'd try some old school stuff; after driving & letting cool down somewhat-remove spark-plugs & read them,,,also look down in cylinders with a scope.
Your A/F sensors may be getting tired also.
How's fuel milage,power,oil consumption ?
Get a good tech to ride along w/a graphing scan tool & record it.....something is bound to pop up.
Any extra information is helpful.

Forgot to mention AF sensors are new and fuel economy seems to be about normal going by what everyone on the forums gets. As far as the startup, i cant remember how fast a good running Z starts up, but it does seem to crank over a couple of times before starting up.
