Thank you so much for taking your time in making this video. It really helped me out since I am on a fixed income. I appreciate it very much. : )

The hose on the spark plug to install them is a great idea.😁👍

@tylerrogan4306 2 года назад

I wish you had shown how to get the thing out of the way to remove coil number 1. That's the hardest part in my opinion. Still not sure how those weird bolts that are shaped like 3/4s of a banana slice work.

I see a a lot of videos on the code p0304. Most of the videos show the mechanic replacing the ignition coils and spark plugs. I have the same code, misfire 4 cylinder. However, I replaced those about 6 months ago. I did a ignition coil and spark plug swap, just to be sure- after that kicked up the same code and problem. Could the problem be the injector?

WHAT IS THE FIRING ORDER ON THE COILS.

@nunyaDbiz 3 года назад

@@williamgriffin4790 It's marked right there under the intake.

@2derekjeter2 3 года назад

I have a 2007 gmc envoy and was changing spark plug #2 from front to back and there was oil inside! A yr ago they changed the rubber seals that go on the top lid there was a long skinny one that went around the edge of the top and 6 that were for the spark plugs it was a kit I bought, it’s hard for me to believe that the same spark plug is having an issue again, could there be another gasket I could have changed that protects the oil from entering the spark plug?

@psautomotive5530 3 года назад

Nope

@danielromo2110 3 года назад

I’m doing my spark plug replacement on my 2002 GMC Envoy just over 100k miles and I found a lot of oil in #1 and a little bit of oil in #2 i don’t know how I should proceed should I just replace the plugs and hope it was the plugs that were letting oil in please help thanks

@robbied5157 3 года назад

That usually means there's a valve cover gasket leak I would get it looked at

I ended up with a misfire on my vehicle after I changed plugs. And I don't know which one of the cylinders is bad that's missing

@waldipup9010 3 года назад

It's a month you've probably done something by now but if you hook up a computer code reader device - $25 or so and worth having - or go to auto parts store for free computer check - code read will tell you which cylinder is at fault . You can then , one at a time , switch plug , then coil from that cylinder with another cylinder and see if the code switches to the new cylinder you chose for either the plug or the coil to identify the culprit .
