I have a 75 mm on mine. Shouldn't cause that. Sounds like the car is running lean and the car is overcorrecting and adding fuel over what it should. A bigger throttle body won't do anything to running condition except make the throttle less sensitive and become WOT more quickly. The real issue is a vacuum leak somewhere. From my understanding you have the stock MAF section or at least closely designed to stock which is all the engine management cares about. Honestly it sounds like a vacuum leak or similar. Unless you changed the MAF housing itself to something a good 1/4" bigger in diameter it's an assembly error not the parts.
