If your inquiring about the plastic cross hairs at the very back of the maf--then no
there won't be any problems. If your electrical wires are split--the maf will not function.
Plug it back in and see--the worst that can happen is the engine will not crank. That would be the case if just one of the electrical wires are broken--if both are broken the car won't crank--if just one the car may crank and the check engine light will come on and the car will go into limp home mode--I drove mine around like that for two days waiting for another maf to come in--installed the new maf and then with my code reader erased the code and all was fine again. If it's just those plastic cross hairs--no real damage done.
