I don't comment on videos often, but this video saved me some money. Luckily I have a scan tool that helped out as well. But the way you explain things and how you go through the process of elimination is outstanding. You have a subscriber for life here! The only thing I did different was move the coil pack in question to an easier location to remove so I don't have to remove the air intake and throttle body when I'm sure it's that coil pack. Great video! 👍

Just had cylinder 1 go dead on my 2015 3.5 with 170k miles after letting the truck sit a while and filling the tank up. Was on highway 1-2 later and the violent shake happened. Flashing engine light just like you showed. Figured it was a valve spring breaking or something. I put msd coils in over 100k miles ago lord I hope that’s the issue. Never thought to swap ‘em around like you did. Gonna try that this weekend. Thanks for your continued videos, I’ve used quite a few over the years I’ve had my truck. Best Ford channel, no bs, just facts and experience from you.

I learned that lesson the hard way about the performance coils on the modern engines. I had previously worked on old Ford V8 stuff, so it was always a no brainer to go with an aftermarket coil and install electronic ignition in place of points. It always helped with performance and reliabilty. I put Accel coil packs on my '94 Saturn and had one go bad within a year. I saved the originals so I put them back on and it ran great until I sold the car years later. It seems the old days are gone when the aftermarket hot rod stuff works better than the OEM. All the manufacturers have really gotten their act together.

Your videos are extremely helpful beyond words. I bought a used 06 f150 with the 4.6. 70k miles yes i know low miles i was getting misfire on #3. Thanks to you i was able correctly diagnose the problem and prevent catastrophic damage . #3 plug was loose almost welded tip to electrode . Replaced coil in #3( looked like boot was burnt) and replaced all plugs. Discovered that 5 a bit loose as well but only 1/2 turn. Installed new plugs properly gapped with the nickel anti-sieze and torqued to 22 ft. lbs. Good to go . Thanks for all you do . I'm glad i didnt launch a plug that would have really sucked although i watched your vid on inserts and would have tackled it. 🙂

Hi buddy love your channel. I bought an F150 used 2018 with 15,000 miles on it. At around 18,000 miles I took it to a dealer because I heard a rattle Coming from under the driver side or in the middle of the truck. I told the dealer it’s more prominent on cold starts so I left it at the dealer overnight so they could hear the rattle. The dealer got back to me and told me it was my cam phasers and they had to be replaced luckily they were under warranty so they replaced them. But when I pick the truck up a few days later I still noticed the rattle when I took it back to the dealer and left it overnight I purposely showed up in the morning so I could point out the rattle. Mechanic listened and he told me it was the exhilarate trans pump and it’s a natural characteristic of the pump to rattle for a little bit until it fills with fluid I would think there should be a check valve to keep the fluid in there it doesn’t make sense to me is he right

Thanks for showing how the software helps to diagnose issues, sure is a lot easier than it was back in the 90's. I have had 7 Ecoboost 3.5 in different vehicles, Flex, MKT, and F-150 and found out the one thing they all have in common are plugs that go bad, especially running a mild tune. I found the problem though isn't bad plugs, but the plug design. If you noticed the center electrode is very thin, needle shaped. That thin point actually burns a hole in the ground strap and while the plug may gap properly that crater actually increases the gap enough to cause plug misfires. I also found gaping to .028 when tuned runs a lot better. I got into a habit of taking the plugs out every 30K miles and running a points file across the ground to remove the pit and then gap to .028. I replace the boots at the same time since they tend to cause misfires too. Never had a misfire since adding it to my general maintenance.
