3.5L Ecoboost Misfires Latest Information
Here is the latest of what we are seeing at the dealers on this issue. If yours is having these issues which may be intermittent take a close look at the items listed. Also this is a ongoing issue which Ford Engineers are still going after. There are a few fuel injector issues but not many it all seems to be on the ignition side of things and the water in the intake from the intercooler is a whole other issue they are still working on and I go over the latest design on that as well. The new issue with age on these is spark plug cracks something so small will likely go overlooked by the technician or DIY type and they usually cause intermittent misfires like this one. It is something to look at if you are having any of these ongoing issues......

Back to the plugs, I haven't done any exploratory work under the hood of
my truck. So the question I have; are the plugs something easily changed,
or are we talking special tools and training?
I never bought the idea of 100,000 miles on plugs, so thanks for the info
on the need to change them at half that interval.

Not to mention cleaning the carb and the linkages plus adjusting the choke.

If the plugs are cracking in some cases, will that have an effect on the COP?
Thanks for posting sir!

Also.. with the aluminum heads are people using anti-seize on spark plugs? Good video. Since I am at 50K, I will be changing spark plugs this week. BTW... after my second stumble/water condensation issue the dealer performed the latest TSB which is the lower cover plate over intercooler. I will see if it makes a difference or not. I haven't driven much after install.

But I know on a lot of FWD Fords (like the wife's 3.0 Escape) you have to take the intake manifold off to get to the back bank.

I watched some of your other videos and I really like your methods of instruction. There needs to be more techs like you that will take the time to video these repairs for people to be able to work on their own trucks and cars out of warranty. Great job!

Just changed mine out. Took about an hour. Super easy. My porcelain didn't have any cracks but the gap on all six plugs was about .040. I used the Motorcraft plugs so there were no issues with warranty. CYFS-12-Y-3 is the plug number. $8.62 ea at stealer.

Is it that easy on the car version of the EB 3.5? I just turned over 70k on a 2010 SHO and every once and a while it seems like it's not idling as smooth as it used to. I figure I can change the plugs and see if it helps as it's due @ 100k anyway.

Thanks. Been a while since I had the cover off on the SHO but I remember it being surprisingly clean. I think in the summer I'll tackle the sparkplugs on it.
