I can see that happening. It's hard to get the rpms high since the engine is pretty strong (at the cost of mpgs ). I have to actually try to get the rpms to 4k when I'm accelerating.Don’t laugh - this actually happened on my wife’s XC - poor idle and hard starting.
PCV system was in good health. But she drives gently. The engine intake tract had oil from the PCV system, causing stumbling at idle, and hard starting, because it was never pulled through the engine at high RPM/boost.
I cleaned the throttle body, changed the oil, then took it out for a drive. A couple of full throttle acceleration runs and the car had visible exhaust. Not really smoke, but enough exhaust to see in the mirror. By the third run that smoke/exhaust was gone.
And so was the stumbling idle.
