First tip, go write your mileage on your wires with a silver sharpie or something that will show up, this way you will know right when you replaced them last.

When I first opened the hood of my '96 Explorer, I was a bit intimidated by the well-hidden spark plugs. I've done most of the regular maintenance on all the cars I've owned in the past, but this looked like a challenge. Before I new it, 50K had clicked over and it was time for new plugs. I did some research and got a lot of good advice, but I discovered that with the proper tools, it's not such a challenging task after all.

Three tools are an absolute must. First and foremost, you gotta get a 5/8" universal spark plug socket. Don't try using a regular socket and a universal adapter, spend a few bucks and get the right tool. I got mine at Auto Zone plenty cheap and nothing else will work as well. A decent boot puller will save broken wires and mashed fingers; my right ring finger had a black nail for month when a stubborn boot finally came loose, directly towards the power steering pump. You'll also need a short length of rubber tubing to simplify installation of the new plugs. The only other basic hand tools you'll need are a 3/8 ratchet and a variety of extensions. Start by removing the duct from the air filter box to the engine intake. Two hose clamps and a few other connections are all that hold it in. It also helps to release the clamp on the air cleaner box, then remove the inner box half (be sure to unplug that wire harness) and the filter itself to get a little more elbow room. That's all the extra disassembly required. Get your new plugs ready by checking the gap and apply a bit of antisieze grease to the threads. I went back with the stock Motorcraft platinum plugs, considering the very good condition the old plugs were in after 50K miles. I started from the front plug on the passenger side. Use the puller to remove the boot. If it's stubborn, try a little silicone spray and twist it until it moves. NEVER pull on the wire itself. If you have access to compressed air, try blowing around the plug to remove any debris. A small brush may also help. Use the ratchet, socket and whatever extension (if necessary) works best to remove the old plug. When it's out, check the condition of the firing end. Look for excessive deposits, blistering or cracking, or oil residue. A dry, beige or gray looking insulator and slightly worn electrodes are what you are hoping for. Keep track of which cylinder each plug came from to trace any possible problems down.


Remove and replace the rest of the plugs in the same manner. When removing the back plug on the passenger side, you may want to remove the entire wire first, since it is quite short and easily damaged. The driver's side of the engine is where that swivel socket will be indispensable, be especially careful around the EGR manifold blocking the plugs. Stick the short piece of rubber tubing on the new plug to ease installation. Take your time and don't cross-thread. Also follow the torquing procedures that came with the new plugs, because the head is aluminum and the threads are easy to strip, which will absolutely ruin your day. I little silicone grease in the boots before installation will make the next removal a little easier. Replace the filter and duct and fire it up. If you were careful and didn't cross any wires, you should have no problems.

I have heard some suggest going through the wheel well to remove the back plugs. That may work, but I didn't have to. You will need to climb up on the engine a bit though, so watch where you step. By the way, since you have that air filter out, when was the last time you changed it?

Why wont my 1996 ford explorer start it turns over but wont start


You need to determine whether or not it is getting fuel and spark. It needs both to start. Remove one plug wire and hold it close to the engine while someone cranks it over. There should be spark from the plug wire. If there is spark, you will have a fuel supply issue. Possible fuel pump/relay/wiring/fuel filter/injectors not working to name a few. If no spark, possible crank sensor/ignition module/wiring.

My 1999 Ford Explorer has the ABS and Engine light lit. When I put on the scanner, detected errors with the following codes: C1230, P0171 and P0174. What problem does my ford explorer?


You will need a book for that...and good luck at finding what you need, the Chilton Books, and others have cut their info. back to maintenance only...for the most part. go to AutoZone, They have a good system, and if you find a friendly Parts Person, they might be able to help you...or you can take it to a known, good, Mechanic...

I have a 96 ford explorer v6 with a pushrod motor and after we replaced the pushrods, the head gaskets, the valve cover gaskets and the fuses, the car will not idle. what could be the problem?


Have you adjusted the pushrods properly? Pushrods generally need to be adjusted after installation.

Not sure how to do this on this model, although I own a 94 Ford Explorer with the V6 4.0 Liter motor.

Basically, when a gas engine doesn't run, you check 4 things, and narrow it down from there.

1. Gas (Is gas pressure good, is gas flow strong enough?)
2. Spark (are all spark plugs firing properly? Is spark strong enough)
3. Combustion at each cylinder (timing, pushrod adjustment)
4. Air Flow (MAF/MAP sensor working? Air Filter dirty?)

I have P0304 code, replaced the #4 spark plug which cleared problem in past, this code a appears very 3 months or so. "89 Ford Explorer "X" engine 180k miles. What should I look at next,...


so what is wrong with the plug when you replace it. is the plug wire OK? if the coil has weak output on that post for #4 it could cause that. I would replace the coil pack and plug wires, just to rule them out. With 180K I'm sure it needs the wires if they are original.

1996 ford explorer, 5.0 liter just changed plugs and wires, it doesn't have a distributor. Immediately it began running rough, check engine light is on and blinks when accelerating. I've never had this...


Good Evening, I don't remember seeing a p9303 code, but a p303 is a misfire code on cylinder 3, I would tell you to double check your plug wires and definitely make sure #3 is sparking. Also be sure to check the spark plug gap since you just put it in that it is possibly a little off. Hope this helps.

1996 Ford Explorer vibrates when idling. Also have noticed that when I go 80 mph, it "jumps" every few seconds. Like it skips a beat. I don't know how to explain it but it seams to "stall" like if you were...


You have a hesitation. A hesitation is cause be either:
1. bad spark plug
2. bad spark plug wire
3. bad or leaky or plugged injector
4. timing is off
5. leaky vacuum hose
