How to change spark plugs on 1993 Ford Ranger 4.0L V6?

I would like to change the spark plugs on a 1993 Ford Ranger with the 4.0L V6. Does anyone out there know if this can be done with typical socket extensions? Or do I need special wrenches to do it. They look accessible enough but I was hoping someone with experience could enlighten me. Thanks.

Changing Air filter and Plugs raise gas mileage?

I was told from a few different people that changing the Spark Plugs and Air Filter on my '03 Toyota Rav-4 would significantly raise the gas mileage. I'm getting around 22 MPG, and I'm pretty sure that I should be getting more. Is this true?
Changing Air filter and Plugs raise gas mileage?
I can鈥檛 say for sure that it would significantly raise your gas mileage but it will definitely improve what you have, but only by a fraction. You are not going to see gains of three MPG, but you might see one or two if your filter was pretty dirty.

Good luck

Changing Air filter and Plugs raise gas mileage?
They would ONLY raise the gas mileage IF they were old and worn. If you have NEVER changed the air filter or you live in dusty area (like farm area), they changing the air filter would very much help.



As for the spark plug, newer cars often use Platinum or Iridium plugs that last up to 100K miles. So your spark plug might not need changing.

Every time gas prices goes up, local stations do a story on gas mileage. Recently they test how much new air filters, plugs, proper tire pressure, clean trunk, etc. all helps. It turns out they all ADD up to only few MPG. It turns out that the BIGGEST difference is from driving habit change.



Jack rabbit starts (quick accelerations) are the worst, and driving on cruise controls are the best. They can improve your gas miles as much few MPG to 10 MPG (or more) improvement (depending on the weight of the car).





Good Luck.
Not only replace the plugs and air filter, but replace the plug wires as well. Keep the oil changes inside of 3K miles and remove any and all excess weight (junk in the trunk) from it.

Oh, check your tire air pressure and tire wear. Also keep your foot out of it. Drive smoothly, don't accelerate hard and start to slow for stops waaaaay ahead of time.



And... yes you can see as much as three mpg improvement.
Well, it depends if the air filter and plugs were worn out and old... Better change the air filter, spark plugs and wires, and drive smoothly. You can see that there's an improvement in gas mileage.
Your driving style adds to your fuel economy too you know. Check out my source below to see what you can do and see if your doing it right for better MPGs on your vehicle.

How difficult is it to change spark plugs on a 1994 Tarago?

If you have never done it, Very difficult. if you have some experiance it's fairly easy. the most difficult part about it is some people have the habbit of removing all the plugs and wires at once. Then they forget how it all goes back together. just do them one at a time removing one wire and plug. Then putting the plug and wire back in. Move on to the next.

if you have the correct tools and remove the plugs when the engine is cold and do one at a time, not to hard to do. it's just a bit fiddly..

How do you change the spark plugs in a 94 acura integra?
just go get one at the parts store when you purchase the spark plugs,...and no need to buy that lubricant that they always push at you...you could just apply petro-jelly....and oil on the spark plugs most likely is the valve cover gasket and groumets...

Do you have to pull the head on a 2004 Ford Taurus to change the spark plugs?

I have changed the fuel filter %26amp; it was full of rust. This stopped the sputtering at low speed 4 about a week. Think it probably needs changed again. While I am doing this for my friend I was going to change the spark plugs. I don't have access to the car right now it is in another state, %26amp; before I buy spark plugs I was wondering if anyone could tell me how hard they are to change.

No you do not have to take the head off.

They are fairly easy to change also.

Typical V6 FWD vehicle - the back plugs are somewhat of a hassle but not anywhere near as bad as some vehicles. You shouldn't have any problems if you've got access to some decent tools.
u shud b able to do them with no prob
dont know the F/T but ford v6plugs arnt that bad the best things to do it with is a good make3/8 drive socket %26amp; extensions you will have more room to work with 3/8 than 1/2. get an assortment of lengths of extensions.
The best way to change plugs in this is to pull the right side windshield wiper box . It takes 3 bolts that are 7/32 of inch and 3 clips . This makes it easier to get to back plugs . I do a lot of Taurus repairs and this is the best way to get your hands back there . If it is a DOHC motor you have to pull the upper intake if it wraps over the plugs . Have not changed a 2004 DOHC so I am not sure but on the 2001 you have to . Good luck and this is about a 2 hour job taking your time less on the 12 valve Vulcan motor . Do not get frustrated it isn't all that bad .
No need to remove head, the back cylinders are a bit of a pain to remove and replace plugs in , but straightforward job. Change that fuel filter also, it will always help, if the last one was plugged you can be sure it will be doing it again.

    replace the distributor cap and rotor if it does not have that then replace the coil pack.

    check your fuel filter
    get a new distributor cap and rotor
    one thing you have crossed a plug wire,it fires but not when the cylinder is on top.you need to check the air flow and the timing .goodluck
    depends on what type of motor but inspect the distributor cap and rotor and if the contacts don't look too marred or corroded put it back and change fuel filter. then ask new question if there is still trouble
    if that particular spark plug is not grounded properly, it will not spark, pull the plug and clean the mating surfaces thoroughly

    How much would it cost to have the spark plugs changed on a 1989 Mercury Sable?

    This car is front wheel drive, 3.8L fuel injected V6. The engine may need to be lifted in order to reach the spark plugs on the front and back.

    Nah, the OHV 3.8's are easy. Pick up some spark plugs on your way over, and I'll do it tomorrow morning for $30. ;-)
