5 Signs It's Time To Replace Your Spark Plugs

[@Voltzaps]

Preventative maintenance 💪💪

[@heffedirte6243]

You ever clean them? Until the last couple of decades, they were cleaned, not replaced

[@bpresgrove]

@@heffedirte6243 I have cleaned the ones in my lawnmower or 4 wheeler before but not my vehicles. I know my granddad would simply clean his but that was decades ago.

[@heffedirte6243]

I like inspecting and cleaning mine....unless they have an "R" in the part number. Then I change them after a few oil changes. The resistors are just junk and not worth it even though they cost 2-6 times as much

[@bpresgrove]

@@heffedirte6243 dang, you know I completely forgot about the resistor designation. Great point! I'll have to write that down for the next time I look at mine and check them. Thanks for that Heffe, you just made my night.

I believe bad spark plugs can cause electrical issues as well as cause starting problems.

[@evanharrington7341]

You listed all my symptoms in minuets with my 90 k1500 chevy now I know thanks very much 👍

[@DKoldies_CEO_Drew_Scumbag]

Oh man, my Corvette would sometimes take a while to start. Sometimes I had to try it 3 times for 2 seconds each to get it to start in the morning. The idle was rough but sometimes was ok. Changed the spark plugs and HUGE difference. Car starts and the idle is so smooth!

[@ChangedUpNowWhat]

Thanks! I’m loving this and I feel like we need to do this for our HUGE difference.

I have a 2016 Chevy equinox and when I start it it sounds like a helicopter really loud and when its been on for a couple seconds it kind of calms down and idles normal. Nothing out of the normal when operating and the check engine light is not on. Any thoughts what it could be? I did notice one coil boot is abnormal like someone stretched it out and looks like someone stuck a large object in the boot and is kind of weird looking. Can that be the cause that simple abnormal out of the ordinary boot?

[@VENKVIEWS]

Very good information

[@johnjerizignacio5528]

I have a funny one, what if the middle cylinder's(Cylinder 2 or 3) spark plug died? Will it also cause a vibration since it was in the middle causing balance?

[@brandonclements4747]

YES, crank rotation depends on every cylinder the engine has to work properly, think of it as a windmill with a chunk of one of the pedals missing or a helicopter missing a blade

[@TheSouthernSkunk]

My truck will stall when I demand more power from it (accelerating / going up hill). It will also occasionally shake and I have to hold the key sometimes for it to start. I got a code reader on it, but it didn’t mention spark plugs. Will bad spark plugs alert a code reader?

[@frostybrew13]

sounds like a bad coil pack possibly. at least that was the situation on my friends 2014 f150 ecoboost

My 2013 Toyota Camry idles pretty high during the hot days and cold days. However once it’s put in gear it settles down and the engine noise is drastically lowered. Car has 156000 miles, I’ve had it 2 years and I’m not the original owner. Although I have most of the records for it on Toyotas website. Could this be a spark plug issue?

[@spicydogsoup]

On cold day it idle pretty high when it starts but warm day no.

Clean the throttle body. I just fixed the same issue in my car doing a throttle body cleaning and idling relearned

[@chadolive1]

Hey Joe, i have these five symptoms lol, and I was wondering other than doing a full tune up which I am not knowledgeably or experience-wise capable of, is there anything else to check that might cause some of these symptoms as well, save some money and maybe narrow it down. When you mentioned a harder start, this is the first time for me. I have a 2009 Hyundai Santa Fe Awd 3.3l has always been a joy starting it when I got it to now, just sounds cool and smooth. Hesitation in rpm idle I have experienced before and now. The hard start is a first and I am at 303,000. Hyundai did a tune up 4 years back and everything was peppy and responsive. Winter is here and a hard start once in a while is and has never been normal for this ride. So, your symptoms nailed everything, first time rough start, sorry for the repetition. Hyundai wants 600 bucks for a tune-up, I would like to save where I can if possible till I can do it myself one day but if not, what will be will be.

[@flinch622]

303k... good luck. On the cheap side, two things for any car and see if anything peps up: change the fuel filter and put a bottle of Lucas fuel injector cleaner [I've had good luck with it] in the tank at next fillup. Tune ups these days are at best cleaning the injectors and maybe the MAF sensor. Your vehicle should be on its 3rd or 4th set of spark plugs. There really isn't anything to tune compared to 40 years ago - computer programs don't drift like points or timing used to do [from chain stretch]. Chris Fix and Scotty Kilmer both have vids on cleaning MAF sensor if you want to do that - use only a cleaner specified for that.

I got a modded civic si full bolt on. Cold air intake with headers and full exhaust. Ive notice it takes sometimes when its cold an extra second to start. Also while idling i notice it running rough like sometimes the rpm drop below 500 then kicks up to close to 1k sometimes. But most noticeable it seems the rpm just jumps from 700 to 1k randomly its not a smooth idle. Ive noticed it running rich but also bad fuel economy, any idea?

[@kevsimoes]

Car definitely needs a tune but idk if the tune will fix the issue or if I should just go ahead and change spark plugs

[@daviddowns7552]

can a bad plug cause actual misfire. it seem like it might? thanks for video.

Of course it can.

[@jmgueeve9159]

Mine starts easy and just stops moving. Poor exceleration and then stops completely but engine still turns on. Check engine light on. Guess it spark plugs ?

Does this also happen periodically? I have a 90's car and it sometimes runs smooth and other times rough and lose torque

[@zestydbd6830]

Same I have a 1998 fiesta and sometimes the car idles rough and has poor acceleration. Then other times it feels normal? Think it's because of the age of the car?

i don’t know if this makes any sense but does the engine eventually get used to running slow after a while? i have the same exact symptoms i was driving like that for a few weeks thinking it was oxygen sensors but turns out it was the spark plugs and now it runs slower and feel a lot of vibration when idling

Toyota Denso but perhaps NKG for Honda. See what OE was then stick to that.

[@kaneclark7171]

Denso or ngk are fine for Toyota,Nissan,and Honda most jap cars use Denso or ngk Denso was the first to make iridium spark plugs and they also make the iridium TT spark plugs The TT (twin tips) are the best compaired to single tip ones I'll choose Denso anyday over ngk Ngk just have the name because there's alot of little kids that own JDM and keep it stock but Denso have been around longer and made more improvements over the years Ngk stole the twin tip design and the iridium from Denso do some research

[@safaricartvideos]

@@kaneclark7171 Ngk and Denso are probably the two best spark plug brands made, and some are probably made in the same factory.

So when I start the car, it idle low and sometimes dies, fine when you’re driving and have gas. At idle or when going into reverse with no gas, it sometimes dies. What you think? Spark? Also mpg is way down, like 9…. 08 G35 No rough idle though
