Thanks for the vid! Preparing myself for the job ;)

How difficult was the plug on left side with the vacuum pump duct to replace??

[@BlueSTI]

I did this to with everything hooked back up but now my car wont stay running. Starts up then shuts off after a second running

[@nicholasnelson5885]

Check the plug gapping, annoying but possible that not enough spark for igniting the fuel in cylinder

[@BlueSTI]

@@nicholasnelson5885 yeah I figured out it was just a bad coil pack 😆

[@nicholasnelson5885]

@@BlueSTI hah, nice bro i figured something stupid just realized this was a 3 year old post lol, glad you figured it out, nothing more irritating than finishing a semi tedious job for it to not work lol

You don't use a torque wrench on your plugs? Just curious how well they sit... I had a Honda Ridgeline that I didn't use torque wrench on and the plug ended up getting dislodged and still firing while all the way up against the coil pack, it melt the valve cover and metal (aluminum) around it and CST me $5k at the shop for new head and work.

Nah I don’t use a torque wrench on the plugs, these plugs have a crush washer on them, when I feel the plug bottom out inside the head I go about another 90 degrees of a turn and that’s tight enough, you can normally sense the washer seating/crushing when you get to this point, if you are unsure and can get a torque wrench in there better safe than sorry tho I guess
