07 Jeep Commander P0300 Spark Plugs & Ignition Coils 

I'm so glad I found your channel! I have an '07 Commander 3.7 and I've started trying to service small things myself, like the mass airflow sensor, throttle body, and spark plugs/ignition coils. I really hope that you keep making videos like these, because they are so incredibly helpful!!!! You are thorough, clear, and informative! Keep it up!

My hope is that most car mechanics would have half of the wits and common sense that you'd showed on this video. Great job.

Love your video. Mechanically challenged people like myself really appreciate your easy to understand direction. Thank you and keep it up!!

Your instruction technique is very refreshing. Many of the male mechanics on RU-vid gloss over some of the smaller things that they assume you already know. Great job!

love the dope commander vids! keep us updated with new issues and things, there's not enough commander vids out there!!!!

This is better than the guys videos I've seen.

This video helped so much. Thank you for sharing. Much appreciated!!

I am not the only one to call it a socket wrench!!!! THE MEN IN MY SHOP THOUGHT I WAS CRAZY🤣

Very good video; Thanks! I may do plugs and coils in my own V8 4.7L Commander.

Great personality in the video, better than watching a crusty old man, keep it up

Ima do this tomorrow!! My jeep been roughly 20k miles . Just bought the coils and sparks !!!!!

Thank you. Unbelievable that other videos on RU-vid tell you to remove the support bar. So glad if found your video.

Great post! Thank you. I have a 09 Commander 3.7 with approx 150k miles. I never opt for MOPAR parts, way way way too expensive, marginal quality. For my ig coils and plugs i use NGK (iridium plugs). 👍👍

Pretty and mechanically inclined great video thanks.

Great video !!! Thanks for posting

Wow your video it’s super nice and easy to view.

This is an excellent video! Thank you!!!

Blow off the engine first. This way you don’t get a bunch of crud going down into the cylinders. NGK does not recommended using anti seize (not applicable to your mopars) ;) Plus you can spray out the throttle body while your there 😎

Guys yes she is very thorough but remember do more research. Always! Because you don’t just hand tighten a spark plug. If you want to do it right find the torque inch pounds needed for your model vehicle, note INCH POUNDS. Not foot punds. Just a heads up. Also just use a ratchet torque wrench. Not what she is using. Some spark plugs can be very hard to come off. Especially if they did not use anti seize on the threads.

Great job thank you for sharing

I love my jeep commander. Has ALOT of miles tho. And starting to run really bad. 265,000+ miles 😱

Very helpful you are a gem! 😁

Anti Seize should cover all the threads.. Where you have it, it will only cover the threads from there up.... What's the milage on the jeep??? Oil pressure still good??

Hello, have you ever had issues with it not starting just get a click. Alternator, battery and starter good. I’m thinking bad ignition switch.

This is what I have to do yet AGAIN 😒 For some reason im having a bad misfire. Changed plugs 3 months ago. Starting has become really hard and when running it will run good till shut off. When start back it misses BADLY. 😤😱

🤣🤣🤣🤣 it lives w your engine...! No sweetheart.. sounds like a recipe for disaster.. live your videos tho! Keep it up

I would Cap off the power terminal on your alternator.
