The first thing im thinking is that one of the coils on the plug went out. I have had that happen several times before to me and its never ran this rough before.
If anyone has any suggestions or things to check for im all ears.

First thing that popped into my head.

Take a close look, those are known to blow spark plugs out and ruin a coil in the process.
It would be really loud if this happened. Coils do go bad on their own all the time as well. By far, the most common problem they have. When they have a misfire, you can almost guarantee it's a bad coil. Replace the bad coil and the plug.

If it's missing oil it went somewhere. I'd start by rechecking the oil since its been sitting, look for oil in the cooling system and looking for where it could be escaping. These trucks sometimes had spark plug issues, look for a partial blowout of one?
They have an even more common problem with ignition coils going bad. Like probably 10x more common than the plugs blowing out.
Is the check engine light on?
If he checked the oil immediately after shutting the truck off, there's not going to be a lot on the stick. It will still be up in the engine.

I have been having the common issue of the heat smelling like antifreeze lately. From what i read thats usually just a leak in the heater coil. Could that have progressed and caused another issue?

Didnt see any oil in the radiator. Plugs were changed about 70k ago. I have never replaced all of the coils, just when they went bad. Im hoping thats the issue.

Heater core...
It won't cause more issues unless you ran it out of coolant, but it sounds like you've at least taken a look at that and I assume the cooling system is not too low?

i had a 97 f150 that I drove 195k miles and lost a few plugs and coils along the way
I have an 01 f150 that i have 110k on now and changed them all at 70k and will again at 130k -140k mode.
When I lost them, it typically ran really rough and went into limp mode as soon as the light came on
Post by: gallion_t on June 03, 2015, 09:53:55 AM
Im now concerned that i might have too much oil since i added about 2 quarts while it was warm.
Ill look more into it tonight after work.

the plug/coil discussion is first. change 'em would wires too... only 2 coils (one per side) not too $$...
for the sake of money, plugs first then wires, if still present go for the 2 coils.... probably burnt off electrode/ big gap from many miles....
passenger back plug sucks..... proper torque on plugs, they rattle out if you don't and can result in pulling thread$$ from head.
after this, bad fuel, filter, fuel pump would be next direction... water in EFI will result in skip/missing but not kill the motor...
any idiot lights/ has it thrown a code?

An '01 f-150 4.6 has 8 coils, no plug wires. :twocents:
sorry mine was a '99/00 going off that info...
with that in mind, easter egg with 1 coil would be cheaper than 8X $$ cost... after replacing all plugs...

Catastrophic converter?
Muffler bearings?
Piston return spring broken?
Was a full moon tuesday.... :chuckle:

got it to oriellys and tested. Missfire on cylinder 3. Went to swap the coil and it just fell off. Then went to pull the plug and it was just laying there. Not threaded in at all. Now i cant get a new plug to start threading. I know a couple of you guys mentioned having blowing plugs. Is there a way to fix it without having to pull the head and retapping the hole?My brother had this happen to him, blew the plug and threads right out of the head. The problem is FORD is pricks and knows they have a problem and wont fix it. Problem being the plugs only thread in about 2 turns and thats it. My dads I replaced all the plugs and could actually unthread the plugs by hand. It was only a matter of time before they blew out also.

Pretty common issue . I recommend pulling all the plugs on a cold engine and replacing them and helicoil as needed . the kit isnt too bad on cost and can be done in the truck . the #4 and 8 cylinders can be tricky but done . Dont use gobs of anti sieze just a pinch . I have the kit if you want to borrow it . I see your up in Everett Jermy up at Auto and truck is a pretty good guy if that works for you . If you wanna give me a ring its (206)522-6100. Corey
Thanks Coach. I might take you up on that offer to borrow the kit. I think im going to call a couple shops this morning and get some quotes on what it will cost to have it done. If its not to expensive i might just have someone else do it.

Is this "Blowing the sparkplugs out" problem specific to the 4.6V8 or does it happen to other ford engine designs....like say the 5.8 in my 95 F-250?Your 351 is fine - this is a problem with the aluminum-headed modular motors. 4.6, 5.4, etc.

I just got rid of my older 4.6 F150 about 6 months ago. Ran great for years and started having the same kind of problems. Went with a new ecoboost and am in love with it. Time to take one for a test drive if you haven't already
Oh I fully agree. I have been looking off and on since about February for a new one. I was hoping to hold out until the 2016s came out and the 15s go on sale. In hind sight I should have bit the bullet back in February during the presidents day sales. Had some great deals then.

Yea, and im still looking and as soon as I find a good deal I will be jumping all over it. Just doubt the really good ones will come out until the 16s are released and theyre blowing out the 15s.
Let us know when you find that good deal. My 1997 F150 has served me well but its list of issues is growing.

Couch, just curious, I always heard when working on tough to get loose parts (or aluminum) to heat it up first.
Can you explain why you do this on a cold engine?

Aluminium grows a ton when hot and the cold head holds its threads better . On those ford's I have had much better luck cold plus you get a true torque on the new plug .one the 9/16 sparkplug models the best way to get them out is with a 3/8 impact gun.. sca red me on the first one but works great .
Good to know thanks!

:yeah:
I changed the plugs in my '01 5.4 at 100,000 miles and after hearing all the horror stories was scared I was gonna cost myself a lot of time and money. The impact works great though and I had no issues.
