I have to agree this is a MAF problem. Subys will do the same thing with the MAF completely disconnected. The first 8 or so seconds the car runs on programmed settings (not the signal from some sensors) then after about 8 seconds it starts to look at MAF voltage. I am guessing its not sending the correct voltage and the ecu is trying to lean the car out. I would check the voltage at the ECU MAF signal pin when its running for that 8 seconds. It should be around 1-1.5v maybe slightly more because of the high idle at startup.
