I take the alternator off. Finally devised a set up that I thought might do it. I took it Mon to my mechanic. Most electronic problems will show up in a computer diagnostic scan, but low fuel pressure won't really throw a diaagnostic code, so that's a potential problem. Carefully start the plugs in their holes. There are in a line across the front. It is almost above the transmission tunnel and well buried behind the dash.
Are you able to fill an easy out drill bit flutes with grease to catch any derbris from the plug. With the hood up and facing the engine. Don't forget to replace your air filter, fuel filter, and pcv valve to complete your tune up. I know he says it's only just a few more bucks but it's almost three times the price of each plug I'll pass. Be sure to gap the new plugs as they may not be properly gapped from the place of manufacture. What spark plugs do you recommend?? Check the temperature of the heater hoses going into the firewall when the engine is cool and see if they warm up together as the engine warms up.
I recommend using something much more stable than this little stool I used. If the pad cannot be pressed into place by hand, use a C-clamp. Use a large C-clamp to bottom the piston, if necessary. Spark plugs for a 98' explorer, if you remove the wheels there is a panel that can be removed behind the rotors that gives you acces to all of the spark plugs. The dealer fix for the blend door is basically the same procedure for replacing the heater core, so it will be expensive. Thoroughly clean the areas of the caliper and spindle assembly which contacts each other during the sliding action of the caliper. Here are my verbatim instructions.
I'm taking my expedition in to be fixed today, I'll get back to you on the cost. We took her everywhere, packed her with 5 kids, dogs, used her as a camper almost a queen size bed in the back! I have never work with no cable plugs. Finally devised a set up that I thought might do it. I'm fixing my truck and selling it. Avoid inhaling any dust from any brake surface! Check and make sure that the caliper piston is fully bottomed in the cylinder bore. Set the gap on the new plugs to whatever it says on your emissions decal on the radiator support. There is a wiring harnes connetor which plugs in to the rigth hand side.
Torque the lug nuts to 83-112 ft. I had to do this to my supercharged 03 Cobra. Attempted to move the saw using a screwdriver that just fit in the drive hole. Reconnect the electrical connection to both the ignition coil and the fuel injector. Make sure that the tabs on the clip are positioned correctly and the loop-type spring is away from the rotor.
Also, make sure you coat the spark plug threads with anti-seize, and coat the inside of the boots with dielectric grease. Time to tear down the engine. The plugs are way down in the hole which is why I use the extension then the swivel. I'm thinking of going Iridium only for more durable higher temp rated materials for this higher compression motor. Do not tighten at this time. Remove the cotter pin and castellated nut from the upper ball joint. I feel that this is the hardest one to change.
Tighten the caliper pins to 16-30 ft. The only thing he forgot to mention is how much pressure it takes to hold the engine forward, leave the dogbones attached, take off the alternator---you're better off. The original platinum Ford plugs go from 80-120k. When I tapped the aluminum, I used cutting paste. Get a loaner tool from Advance or Auto Zone like this. No wonder I had missfire. Tighten the new spark plug and reinstall the coil over ignition coil.
It comes of hard bu keep at it with slow steady force. Next you can actually remove the plugs. Once you remove the small bolt which holds the ignition coil in place, use your compressed air again to blow out the spark plug hole. I can't stress this enough. To avoid overflowing of the master cylinder when the caliper pistons are pressed into the caliper cylinder bores, siphon or dip some brake fluid out of the large reservoir. Ford knew about the problem, but never recalled the engine because so far, it has not been life threatening. I have been using a magnetic sparck pluck socket that works well.
