I suggest you post more info about your issue. Could be a dirty MAF... *shrugs*

If your defroster is on, that could be from the AC compressor turning on.

Could be dirty throttle body, dirty MAF sensor. NOTE: only use MAF sensor cleaner to clean the MAF sensor otherwise you may as well just buy a new one.
