How are you doing power wise? Does it feel underpowered? Do you feel it vibrate from a misfire? Could be a weak fuel pump, clogged/restricted fuel filter or clogged fuel injectors.

A set code does not identify an exact problem, it only points you in the general direction of the problem.

You need the proper year FORD SERVICE MANUAL (and referring TSB's) which will give you the proper diagnostic charts/sequences to follow.

While the manual is not cheap, it is cheaper than randomly throwing expensive parts at it.

Not yelling, don't think I know it all but there is no other logical way unless you know a certified tech that has years of experience and works for beer.

Which engine does your Explorer have, and is it a 1997 model year like your username would imply?
