Well, I put a new MAF sensor on monday and so far no SES light on! It used to come back on the next day after resetting the light. I also replaced the seal after MAF to the air tube and the seal from the air tube to the throttle actuator- now things are really snug in those places where before even though the clamps were tight it still was not snug. I also replaced the hose that goes between the throttle actuator to the purge valve- just seemed to be the next weakest link for an air leak Hopefully this will help you guys in trying to find a possible air leak after ther MAF sensor.
