I’m pretty sure I need some, if not all, of my ignition coils replaced.

It’s a 2010 model. Any ballpark idea what it will cost if I did replace all at once? I was told that the 2010 model had funky coils that might be more expensive? Knowing my luck, that sounds about right

Also, where would be the best place to take it to in BR for this?

They’re super cheap parts. Maybe a few to several hundred depending on if the shop fricks you

I was told they’d be in the ballpark of $60-$80 per coil because of the year of the truck.

How many coils does a 2010 F150 even have? I have no idea.

That depends on how much blinker fluid your truck requires.

One on each cylinder.

Notorious for going out at 6-8 years and/or 120k miles.

Motorcraft OEM coil packs seldom need replacing. It's usually the coil pack rubber boot, coil pack spring, or spark plug that need replacing. Boots and springs are about $3 each. Motorcraft coil packs are $50+ each. The cheap chinese coil packs are a crap shoot. Some don't work right out of the box.

The 3 F150s I have owned and 450,000+ miles zero coil packs replaced. Coil pack boots and springs replaced when spark plugs are changed.

Under 150 if you do it yourself. It is super easy and I have no mechanical skills. Replace tour spark plugs while you are at it

My truck is “sputtering” between 45-60mph and have been told the issue is most likely coils and/or plugs.

This seem right to yall? Truck runs just fine otherwise.

What engine? Miles? Check engine light? Have you had the engine codes checked?

A bad coil pack will cause a check engine light after X number of misfires indicating which cylinder is misfiring. Firing the parts cannon at an unknown problem gets expensive and often doesn't solve the problem.

They fail and it's not uncommon. I just replaced one on my F150, hairline crack on the top of the coil housing let enough moisture in to finally kill the coil. I bought two and keep the spare in the glovebox, eventually I'm going to replace all of them as a few are at the edge of specification after bench testing all of them to find the faulty one.

This thread is a reminder to me that when my F150 gets about 8 years old, I need to trade it.

This. If a coil is bad the engine light will come on. Might need a fuel filter change.

I’ve changed my coils many times. It’s easy. An 8mm bolt holds it in. Unsnap the clip and it comes right on out

Don't break a plug off in the block when you do it

It's such a shite design they had to make a special tool for it

Would a need of ignition coils replaced be a remedy for the error code P0302?

Coils are easy, but the plus on a 5.4 are a nightmare.

I could swap out a 4.6 in the time it takes to change 5.4 plugs. You will break a few and need special tooling.

You usually get a flashing red check engine light.
But it will flash with bad coils not stay on constant.

It's easy to do. I did it on a 2008 and I'm no mechanic at all. One screw and they slide out basically. Watch youtube and you'll see how easy it is.

It could be the coil or the plug.

1. Clear the error codes
2. Swap the #2 coil with another (remember which one of course).
3. See if the code shows up as they other cylinder P0304 or whatever.
4. If so, the coil is bad. If you still get P0302 then it's probably the #2 plug.

If you have the 5.4L Triton it's a nightmare to change plugs yourself and a shop will quote you probably 1k'ish.
