Ever since I swapped to my pi intake I've been having hard cold starts. Sometimes I wonder if it'll actually start at all. Did some research and decided to first unplug my MAF before anything and sure enough she fired right up. I guess it got bumped during the moving around of parts. I've cleaned it with isopropyl and It's definitely clean. It's no good. Anyway, I have another MAF from my 98 4.0 explorer sport that I know is good just laying around. Part number is F57F-12B579-DA. Can anyone cross reference this for me? I found that they were used on 94-95 GTs for 19lb injectors. Can't find any cross info for newer 4.6s though. I can't imagine why it wouldn't work. I just don't want to take the chance a lean my car out. I'd much rather not buy one if I don't have to. Any help is appreciated.
