What would happen if you did a bad spark plug job? I recently changed the spark plugs on my 02 Ford Explorer XLT and after i did that ive been hearing like a repeating, loud whisper sounds from the left side of my engine. Would that be the cause of a bad spark plug?
Yes let’s look at a picture of the differentials to replace spark plugs. Btw none are that easy. You almost always have to pull the fuel rail
@Edel99 check if they are the regular type or iridium/platinum…you might not have to replace them that soon.
Cool! I have an 06 Pt Cruiser with 32k and it’s time to change the spark plugs (according to the owners manual).
Whatever you do, don’t put a lot of pressure on it, or you can easily break the plug off, then it will be 10X harder to get out.
Thanks, I finally got it. Now Im just having problems starting the damn thing :P
have you tried any Penetrating blaster? Give it a good 3-5 second burst and let it sit for at least 30 minutes. If that doesnt work you can get a breaker bar, or cheater bar as its sometimes called and that should give you enough leverage to turn them.
nice vid
Any idea how to undo a spark plug that hasnt been changed in years? No mater how hard I try, I cant seem to remove the spark plugs in my engine. Theyre completely seized into the engine. I have a feeling its because the engine is cold(due to weather) but also because it hasnt run in months (the engine doesnt work). Any ideas what I can do, to remove those plugs?

From what I know, black smoke means that the motor is running to rich ( timing, spark plugs, even wrong octane of gas can cause that).
Blue smoke is usually oil is burning (too much oil has been added to the engine, bad piston rings).

If it doesn’t say in the manual then call the dealer or an autopart store and they should be able to tell you the OEM replacements or what came with the car from the factory.
the code scaner he used will not erase codes,u an get it done for free at ur auto parts store!
5-10 depending on previous aftermarket(perfomance) items installed although the increase would be significantly less than that on an otherwise stock vehicle.
generally you would see a 1-3 MPG increase by replacing spark plugs in a vehicle with worn, dirty, and/or fouled spark plugs and for the less than 20 dollar replacement spark plugs can help achieve peak fuel economy
I f your car is OBD(On-Board Diagnostic)-I equipped (generally 1987-1994 model year) or OBD-II equipped the service engine soon light will be activated by the computer to notify you of possible problems with your car. Running rich(too much fuel in the air to fuel mixture (which is perfect at 14.7 to 1 less than 14.7 to 1 is considered rich while higher than 14.7 to 1 is lean) will cause problems with emissions and fuel economy triggering the service light
Bloody good mate, nice vid easy to listen to, and informative.
Good info, thank you!
how much MPG would it help to improve?
your running rich or burrning oil is the service engine light on?
NGK platnums most likely most Japanesse cars use NGK or NIppodenso plugs and they are almost equal in performance so niether would hurt. ive got a 97 eclipse (Mitsubishi for a time also used Champion brand plugs from Chrystler)
08 mitsubishi eclipse v6
it is almost always the first on the list, the seconed is a suitable sub should the first become unavailable. What kind of car is it I might no what plugs it needs
that’s the thing, it doesn’t….well not exactly. It only says the model number, but I wanna know what kind of tip it has since in the maintenance manual it tells you to replace different types of spark plugs at different times.
the owners manual tells you the brand that the manufacurer uses
burning oil, running on to much gas not enough air, burning coolant.
