actually here's our text.. I think it explains it all. He's about to set it on fire. :****: I told him "my last resort is to start a thread on hardline.. Smartest bunch of fukers I have ever seen, someone will have a answer I promise." So here we are. 5.4L ford. Actin up.

Sounds like ignition problems! plugs, wires , or coil packs not sure what it has but that's where I would start maybe fuel filter!

Elliott · Sep 25, 2015

Aren't those motors bad about spitting out spark plugs ?

WeezyLoudPack · Sep 25, 2015

Also PCV valve and elbows and fuel filter have been replaced

That's what I've heard. But luckily mine haven't yet

Also, P1309 "Misfire monitor disabled" and random misfire codes is what the scanner told me.

Got a friends doing the same thing, turned out to be coil packs.

Did he have the P1309 code also?

Start with a set of coil packs. If the plugs are still in the head.

Gonna be a coil.

Eddyj · Sep 25, 2015

Coil, broken spark plug, that many miles check Egr system. ( if he didn't clean intake when he did head gasket)
I replaced a timing chain on a 5.4 with 200000 miles and it was dirty as hell from Egr.

Buy all 8 coils and plugs or chase the demon for days. Also make sure the heater hose pass side is no leaking on coils. Or if you have a snapon scanner you can go into mode 53 section 6 and try to identify which cylinder

Other than coil packs and manifolds rusting off these are actually good motors, the coil boots have a spring with a carbon tip on em that contact the plug to the actual wire, these springs become weak and the tips wear down which can cause intermittent misfires, id change em all, jegs and summit sells a complete accel kit pretty reasonable

X2, Accel coils for these used to be the cheapest option. It's probably got water in at least one spark plug tube.

If a spark plug blew out, you would know it by how much noise it makes.

It has a bad coil, no doubt. These engines are notorious for it. Very hard to tell which one without a good scanner though. I will have my scanner with me this weekend, actually gonna be in douglasville tomorrow. Pm me I can swing by and look at it. I will try to check back on here tonight.

Dam that's a hell of a nice offer.

My brother had to replace 1 coil pack and 2 plug boots on his 03 expedition with 5.4. He was getting random misfire til he carried it by a local shop to pin point. Took guy 20mins tops to locate problems.
