I am going through the process of replacing the boots and springs on all of my original coil packs. The contact on the coil pack end itself need is heavily corroded on all packs I have pulled so far. Other 5.4 owners claim that the coil packs generally do not actually go bad, just need cleaned + new boots/springs.
Autozone scan will not specify which specific coil may be bad. It's just a generic code for bad coil or coils. Doesn't tell you which specific cylinder or how many may be bad.
@@BLUECOLLARGARAGE I was wrong, after some research. Autozone did show code PO353 when I took it there today. Which is cylinder 3. Bad connection possibly. Or bad coil, or both. I took it to Midas the other day and they said the intake manifold was leaking. Which I had them replace. They also said 2 female ignition coil clips were bad. But we only get one code for cylinder 3. I don't trust Midas. And I'm not sure the intake manifold really needed to be replaced. So, I guess I need to address #3, fix it with a new connector and'or new coil and see what happens. Any suggestions? Thanks.
Found the problem. The number 3 coil clip connector wasn't plugged in. The plastic tab that clicks and holds it on is broken. But when I reconnected it the motor ran perfect. I'm just going to put a zip tie on it to hold it in place for now. Number one connector needs the same thing. I'm convinced Midas left that connector off so I would come back for more work. Because they told me "all" the ignition coils and two connectors needed to be replaced. Can't trust anybody these days.
@@badgumby9544 good find yeah I bet they did leave them unplugged thinking you'd come back and they would know right away what to replace. Like you said can't trust anyone these days especially mechanics. Those plastic clips always break due to the heat their exposed to ziptie will work just fine.
All OBDII scans will give you the cylinder number in the code. On an F150 after 1997, the coil is directly on the spark plug above that very same cylinder. Ergo, P0301 = cylinder/coil 1, P0302 = cylinder/coil 2 ETC. On most cylinder related codes it is the last number.
Nice video, thanks for breaking it down for layman like me

Great new for me. Thank you 😊
How do you get to coil #8?
Thank you!!!!
Ow do you replace coil #4 ? Got that issue right now..
Same way . just look up cylinder number. And remove 7mm bolt holding it in and unplug old one and plug in new one .
When you put the new coil pack in is there supposed to be play where you can slightly turn the coil pack Will this cause misfire
No it shouldn't cause an issue. That's why they use to 7mm bolt to hold the coil pack down.

Did you try advance auto parts or orielys?

Use ford coils nothing els
Yeah parts store didn’t have motorcraft in stock and couldn’t wait on shipping so had to go with store brand.
