You need to check your plug wires for cracks and wear. The best way to know if they are bad is to run your engine at nightr and look for any time of blue arcing spark coming from any of the wires. I believe that replacing the wires will solve your problem.

My 1999 Ford Explorer Sport 4.0 SOHC will cold start and idle till the gas runs out.Will not restart unless it is floored and then miss


Sounds like upper o2 sensors are bad. May also be other things like a dirty idle air valve, fuel regulator, fuel filter, air filter, etc. Do all the maintenance then re-evaluate. And the problem with o2 sensors may not give you a code.

Fuel Filter for Sport Trac


If the car is running good no engine problems or poor gas mileage I wouldn't worry about it. This is done as preventive maintenance. Every tune-up parts have replacement recommended periods. Ignition components, all filters and lubricants should all be replaced the most every six moths depending on how much you drive. Its all common sense if you check your oil and its black its time to change it. If your brakes are screeching same thing and if it been six month probably well over 15,000 miles since you replaced the fuel filter it'll be a good idea to change it.
