I can’t wait to open my own car shop ONLY working on Hemi Engines and Nag1 Transmissions. I want to do honest work. Chrysler offered me a job, but I don’t want to start off upselling shit.. I want to do honest work & save people money. That’s my end goal.

I like getting these videos at different/ random times throughout the month, less stress on you to make and put out and we still get great content 👍

Just the fact that I can see my engine once it has been removed is worth its weight in gold.
Very informative and likeable channel that definitely deserves more subscriptions.

2008 Dodge Charger SRT8 6.1L Hemi - 49k miles
Error code P0300 - Last year and replacing the spark plugs fixed the code.
Yesterday i encountered the same code P0300. Couldnt be the spark plugs cause they only have about 5k miles on them. I used Lucas Fuel booster and after a day of driving it fixed the code issue.

Well done.. AND yes, great tip. It happens.... I would like to add that I also had a cam sensor going bad that would register as misfires. Changed sensor, all is well.

Another thing to look at in regards to the coil packs is the electrical connectors. My first misfire issue with my hemi was caused by a buildup of dirt inside the connector itself. Once cleaned, it was all good again.

Came at the right time. My 17 ram 1500 developed a #3 misfire. Fearing the worst but praying for the best outcome

Thanks for the video, I just had to do this process with my 06 300C on cylinder 2. Mine ended up being a short in the wiring to that injector, I ran a new wire from the pcm and good to go!

Your presentation on every video is very clear and concise not to mention helpful! Thanks for sharing your HEMI knowledge!!

this man is really doing God's work

I'm having a cylinder 5 misfire currently on my 2010 charger r/t & this information was beautiful! Thank you sir!

[NanoDiaz]

excellent explanation, thanks for sharing your knowledge! don't stop doing this!!!
If the Hemi engine vibrates at idle, could it be a misfire?

Love the videos! Have a few saved as a tutorial when I replace the cam and lifters on my 2013 srt8 superbee. Thanks for being so in depth with everything. Keep up the great work!

Dealing with a P0303 when cold starting 2012 Jeep Grand Cherokee 5.7L. This was super helpful. Subscribed. Thanks for this video!

This is a great video Sky, one of your best! Really informative.
On a separate note, your revamped Reignited shirts are really great quality and super comfortable. I wear them all the time!

Bro, love the content...still waiting for the 1500 cam/lifter replacement tutorial lol. I think it would be your most popular video to date. It'll be all over the forums if you get specific in a walkthrough type video or even better - video series...God bless. Truly appreciate the effort you are putting in.

I really enjoy your videos don’t even change how you describe the steps and reasons for things that fail and how to work on it. Very good and easy to understand. Definitely going places with your YouTube content.

a guy had done the same thing of diagnosis a misfire on a HEMI, he changed the spark plugs everyone was working so he switch up the spark plug that was supposedly misfiring and that spark plug was working so he looked at the coils check those and they were okay, so he checked underneath the covers to see if it was a roller brushing up against the rockers which would make a negative charge those looked good, So he went back to his diagnosis tester looked at all the sparks through each cylinders and those were okay, so he ended up just getting a new PCM with a 50 dollar install for the HEMI with it's VIN connected, then checked the rest of the codes that came up after the install and everything worked like a charm! Pretty cool stuff.

I’m working on my Magnum. Thanks to your videos I’ve had the confidence to do 65% of the rebuild myself. The rest was done by a engine shop. Now my issue is Cylinder 6 connector isn’t giving the meter any reading. I’m getting a code for a misfire. I purchased a new engine wiring harness but it came from a Chrysler. I learned the coil packs are different from dodge and Chrysler. Any suggestions on what I should do? Try Chrysler coil packs or find someone to rewire the harness? Thanks for all you do for the home mechanic like myself.

Thanks for making these videos. I have been sharing them with my boys to help them get a better understanding of what is going on and what to look for. These videos are a great teaching tool!
