Sacred Cow BBQ says:

Subscribed.Thanks. Question. I have a misfire on cylinder 2. I see you're replacing the coil pack. What about the ignition coil? Does that need to be replaced too?

Amanda DaSilva says:

How do you know when it needs to be changed? My car has no pressure when i press on the accelerator. It hesitates a lot before it slips into the Drive gear. Finally pushing the vehicle to move.

Angel Cortez says:

I had a REAL HARD time putting the electrical connector back on. It only went on about 98% but not enough to hear a “click”. The Red tab wasn’t able to slide over. I spent over an hour trying to fiddle with it.. I ended up just putting it all back together without sliding the red tab. I don’t know what to do.


thank you. very easy job, except for that dang clip! i am not a fan of the stupid red tab! finally got it though, job was a success!

Thanks for the video. It helped me with changing the coil pack and plugs on my 2004 Grand Cherokee.

Cory Granger says:

It will shake but won’t stay running now it will turn but not start

John Krebs says:

Your tip on removing the electrical connector saved me a lot of aggravation, thank you !

Gerald Diserens says:

I got the coil pack off with no problem on my 2004 Jeep Grand Cherokee but I cannot get the plug off. The red tab has been slid to the side but the plug will not release. Any thoughts?
Great video and easy to follow by the way.

John Howard says:

Proper way to describe removing electrical connector: It is a slide-lock mechanism. Simply slide or pull it back. Nothing to do with "side" or "up". If you can't see the tab, simply stick your thumbnail where you think the tab is and slide it back.

Paul Patton says:

My 04 Limited gives a little shake when idling but no codes showing, should i just change the air filter and see if car doesn't shake anymore before changing spark plugs?

Adrian Z says:

Help. Jeep wont start after replacing the coil pack. I followed everything on the video and reinstalled my old one and it started. New one wont work but its the right part i got it from autozone
