No the car is running fine if I had a bad IM gasket the idle would be all up and down and I would get both PO171 and PO174, not just one of them.
Anyways thanks for the info., but I will continue to clean the MAF everytime PO171 comes which isnt very often.
By the way with replacing the downstream many people have said that wasnt the problem most likely, it wasnt my idea though the shop I took it to replaced it.
