    I would clean MAF sensor, throttle body, and inspect for possible vacuum leaks. If the fuel trim is high on cold starts spray a little brake cleaner around the intake tubes and manifold, if they come down to normal levels you have unmetered air entering the engine in that area. Fog it again and see where you sprayed that made the difference and inspect it
