I would say your running too rich, but you say its ok. Whats your set up? You have some sort of wide band? Are you running a very large Maf housing and fuel injectors? Does your car ever stall out when you push the clutch in and it doesnt catch the idle?

If so you may be soaking the CC with fuel when you start it back up.

If this is happening, Floor the gas 100% before and while turning the key to start it. As soon as it starts you have to get OFF the gas asap so you dont rev teh crap out of it. Flooring the gas when starting puts the car in a safety mode and it doesnt inject any fuel. The engine just starts on the unburned fuel in the combustion chamber. If there is too much fuel it will wash all teh fuel off the cylinder walls and the pistons will polish the crosshatch, your rings will go and you will loose compression.

Change your oil asap. If you cant figure out whats going on Id change the oil much sooner then normal. oil and fuel dont work well together.
