Fantastic!!

R.p.m going up and down at idle whats that problem??

I have a pump in the tank and a high pressure pump. If I scan my car with Carscanner, I can read the commanded rail pressure, and that changes a lot, depending of the amount of throttle I give. Either 280bars at idle, or over 1000bars when I go over 3500rpm...

Also can cause a misfire

Grasias por el video

You said a "dark gray matte coating on the spark plug insulator", isn't the spark plug insulator the white ceramic part of the spark plug which is outside of the combustion chamber? Is the question worded wrong?

Great video right to point

Ya all know nothing more than you did before watching this useless viceo!

Yup my infinity does all this. But today in the morning I was driving and it turned of by its self .

Why these bladybackgrund noiz?

Got a set of AutoLite 45's ready for my 427FE! Thanks for a nice, short, to the point video!

Why does I have to change a spark plug after every couple months. It’s not some cheap brand either it’s denso the came with the car . 20$ each and I’ve replaced 6 new ones at the beginning

Very helpful.

Thanks for this video 👍

Why are they saying that the spark plug last longer than chaging them every year or so

Poor mileage... Poor acceleration... I have these two...

On my spark plugs, the corona stains are flat out BLACK colored.

You’re the man

Looks like I’m spending some more money haha thanks for the great instruction

What a great information 😮 my car problem all of the above 😅 thank you

I like how you explained the difference in a nutshell.

Yessss I needed this. Thank you

Forgot we learned that in scouts. And one day hanging the clothes line back up after the rope broke I could not believe that I knew this bow🤦🏽. Seeing this gave me a good feeling of what the youth of our Nation must learn.

Awesome brother!

You were right 🥲

I hope it is

Thanks helped me know what to look for when going down the line of possible issues.

@romeparrilla8307 0 seconds ago PLEASE HELP ME,I was wrong,i did applied Anti-Seize On Spark Plug Threads ON MY 2001 TOYOTA TACOMA ,ITS RUNNING FINE BUT SO IS IT TOO LATE FOR ME TO REMOV

Been using CU anti seize on plugs for 40 years. Always worked 100%.

Dumb

Spaciba🎉

Very nice discription of each one. ⭐⭐⭐⭐⭐

Thanks only need to watch 36 seconds all of the above😂

Mmi 😊

So is this what cause the diagnosis to say system too lean

Dudeeeee you blessed me with this video I swear 😂🫂

Change your oil What a concept.

Do you need to change coil packs every plug change/ tune up?

Not helpful

No demo... But there is lots of important information on this short video... Kudos... Better than most longer videos with demonstrations.

Honda's service manual says to use antiseize, provides a torque spec, and specify NGK plugs. NGK say no antiseize and provides an angle tightening spec. Probably either are fine, but if I'm putting them a (my) Honda, then I'm using Honda's recommendation.

Thanks Peter, we are very keen to buy some of your sparking plugs as soon as my Uncle Alan returns from Portugal

For years, the car makers recommended using anti seize on spark plugs in aluminum heads, while the spark plug makers were against using anti seize, because they claimed it affected the spark plugs' heat ranges. I have seen some AC Delco spark plugs come with anti seize on them in the box since then though.

There are zero comments because there is zero information here.

What about sudden jerks

Thank you

Well im just needing some ID: 1/2in fuel grade hose for my celica pcv system lol..the only fuel grade hose with those spec are the boat hoses...

My idling is not rough but when I go accelerate my car shakes

Ironically I'm here cause the autolite iridium xp plugs I took out of my kia soul had Corona stains lol

I never thought a bad spark plug could trigger a Check engine light to turn on.I always thought a bad ignition coil would cause your check engine light to come on.
