Re: 98 explorer, bad idle and rough start --MAP, MAF?
Since when you unplug the MAF the engine idle speed goes up to the same range that you can hold the throttle at and still have a smooth idle, I don't really think the MAF is the culprit. However, it is very inexpensive to clean the MAF and that might be worth a shot. If holding the throttle to keep the engine at around 700-800 rpms will not keep the engine idling smoothly you probably have a vacuum leak or other misfire issue. If at 700-800 rpms the engine idles fine, then I think you're looking at the IAC.
