2003 Toyota Camry 4 cyl Two Wheel Drive 69000 miles

I have been having a problem but it is in no way effecting how the car drives. In the morning, after sitting all night, I start my car and grey smoke comes from the exhaust. It ONLY happens after sitting for long periods of time. After 4 hours, if I start it, it is fine but if I don't drive it at lunch and it sits all day it does it. I have added gas treatment to my gas to no avail and changed gas grades for two or three fill ups but nothing. What can this possibly be?

Hi there,

I would start with having the exhaust emissions inspected to see what is actually coming out the exhaust, also have a scan done as not all faults will set the check light off, start here.
