The first thing to do is look inside the air intake tubing for signs of excessive oil. If the tube just short of the throttle body and after the intake from the AOS is covered in oil, you have an AOS diagnosis...and it is a messy Do It Yourself job but not rocket science.

But having sat for weeks, condensation in the exhaust can lead to grey smoke until the exhaust gets hot enough to burn out all that water (ever see a car driving along with water pouring out of the tailpipe?).

Look at the oil? Milky or normal oil look?

Look in the anti-freeze overflow/expansion-tank. Look normal?

So look at the intake and, if that seems ok and the fluids are ok, then warm it up and see if it goes away.
