I would suspect a vacuum leak somewhere if it won't stay idling. Check all vacuum connections make sure there tight on the nipples no splits in the hoses. Check intake tube for cracks.

Also check the MAF to throttle body tube for holes. I had a 91 explorer with same problems. Quick fix- wrap holes with aluminum foil then electrical tap, until you replace it.
