Another great information and tutorial from you sir...I love the music❤️

Hi, I think we need you to relocate to my area .You are a well trained tech !👌

Thanks. Good video..

The way it sounds over the video i would be checking to see if there are any rods poking through the side.

Nice informative video 👍 what scan tool are you using to get all that data?

How are these engines on these vehicles? I really would like to know I’m having a hard time trying to figure out some information about the engine. Can you help me out please

yep that's the exact symptom

Billy Carson?

im having issues with mine, it keeps pushing white smoke out my exhaust if im at high speeds and makes a puttering noise and kinda misfires if that makes sense it has been working fine before i drove it a few hours on a trip

Was hard for me to hear through the speaker but was there a buzzing sound as well as the taping sound? mine has one that comes and goes and is pretty much continues while driving wondering if I’m having the same problem

Another awesome content 👌🏼👌🏼 bro I want to help you on your channel COVER.

I did all my coils and still get a blinking engine light and a code p0300
