First I'd like to say, I'm glad i found this site !! Hopefully, I'll find some answers to my car problem.. I own a 04 LS with 39,105 miles on it.. one week ago, my car went into ETC fail mode, I stopped by auto zone to check the codes, and this is what poped up P2107 Throttle actuator control motor processor. what exactly is that ?? And what's the best way to pin point the problem ?? please help me and any information would be greatly appreciated :(

p.s. this has happend twice, first time the CEL did come on, second time no CEL

Hey, another Orlando LS taking a sh!t. When my LS had its first coil problems it threw a throttle code. The dealer replaced the entire TB and it still went into failsafe. You may have a legit TB problem but its most likely a bad coil. You should be able to take it to the dealer for free if its a coil issue.
 
switch your #1 and #4 coils(passenger side front and back), when the #4 coil starts to break down, it emits RF interference that the computer incorrectly diagnoses as a TB issue, and causes the car to go into failsafe mode, if this fixes your problem then just replace that bad coil and call it a day.

at first it might happen weeks apart, then it might happen twice in the same week, then all of the sudden it will start happening a lot (like five times in one hour)
 
Replace all of your COPs (coils) and spark plugs. Trust us.
 
Thanks everyone for the quick reply's.. I was just reading here that Ford has a warranty 07m07 for bad coils, my question is, is that only for the 03 LS.. ?
 
Well lucky for me I own a V-8.. just to clarify, we are talking about the ignition coils right ?
 
No, your car is covered also. Go see Ray at Central Florida Lincoln on Colonial Dr. They'll cover the repair.

One other thing.... make sure they give you a free rental while yours is in the shop.

Yes, COPs (Coil-On-Plug), one per cylinder.
I would go to the recommended dealer above, not all of them seem to know that marginal COP can cause false TB codes.
 
Wanted to mention this as well, my car would spit an stuttered, and then go to failsafe mode while I was driving around 30-40 mph. never on a cold start up, always after I've been driving the car for a while..

I hope this makes sense to you.. Also what is TB ?

TB ?? Could you give a bit more details as to what that is please
 
Throttle body. If the dealer doesn't know about this little issue, they will say it's your throttle body and charge you to replace your good throttle body. It's happened to a few members, including myself.
 
Thanks for letting me know.. Now I'm worried that the stealership will try an tell me it's the TB instead of the bad coils, just so they can charge me ..
I'll keep you all posted as to what happens..

yep it is sounding more and more like coils

that is why i would try the coil switch i mentioned earlier, i bet the spitting and sputtering will stay but the fail safe will go away, then they cant say that it was the TB, unless of course you have many bad coils and you just end up putting another bad one in that location

if they do try to say that it is the TB and not the coils make sure that they actually did the proper stress test that they where supposed to do

Asialee I'm going to differ from everyone else saying replace coils and say you might need to replace your TB (throttle body). They went electronic on the 03-06 years, and lots of '03 LS' seem to have an issue with it. (I know you have an '04, just saying to watch for it)

The problem mine had was the part went bad and would overheat. It would run OK at first, but after driving it a bit it would get too hot and do exactly what you describe. My mechanic (not the dealership) diagnosed the problem. The throttlebody was wicked-hot to the touch, and it shouldn't be.

So that's my .02¢
 
so you would replace a $600 TB before you would replace a few $50ish coils? not to mention having the customer service program potentially take care of the problem completely free of charge

i'm not saying that its not the TB, but it does seem to be a lot more common of a problem with the coils, and the high rate of TB issues could be contributed to the common mis-diagnostics of the car claiming a bad TB when it was something else.

he is describing the problem i had with my 03 exactly as well and mine did turn out to be just a bad coil.
 
It is not uncommon when the #4 COP is going out it can produce RF (electrical interference) that is picked up by the computer in the fire wall behind the glove box and produce false trouble codes, not that can't be the TB. your 04 is under the extended warranty, have a dealer look at it now that you have this information.
 
Let me give a bit more information as to what's going on here, the first time the ETC fails safe mode came on, so did the CEL P2107 and Misfire 3 , in other words coil #3.. the very next day, i had an appointment to get my oil changed, so I had my mechanic replace the #3 coil.. my car drove fine for ah a month or so till it happened again, even after replacing the #3 coil, I would still have hesitation on acceleration.. and like i said before right before it goes into safe mode, it studders like i have really sh!tty gas so to speak lol
 
p.s. as for me changing the coils around, I have no idea how to do that.. with that said, I hope you still take the time to kindly help me with my car problem..
 
well the car does its best to try to guess what cylinder is misfiring, some times it doesn't even know that it is misfiring, or it just guesses wrong, or you may have more than one marginal coil

to change or swap coils you need to remove the coil covers (8 or so little 7mm bolts) then remove a 7mm bolt holding each coil down, then unplug the coil and then pull it out

All very true points. My experience (and many others' I think) has been that once one goes the others won't be all that far behind.

Yes, the 03's and some early 04s had a design issue that could lead to the problem you described (not all of them will fail). However, the symptoms for that are pretty consistent, and I don't think that's whats going on here. The fact that there was a code for a misfire pretty much seals it, I think.

That's okay, no one can do everything.

You need to get the coils fixed. Besides your current issue and the reduced performance and mileage, it is also reducing the lifespan of your catalytic converters.

Joe, what do you mean by it's reducing the lifespan of the catalytic converters ?

Every misfire sends some raw gasoline into the converters. This gasoline then burns inside the converters. (The surfaces inside the converters are hot enough to ignite the gasoline.) Burning gasoline inside the converters makes them even hotter, too hot. This excess heat causes some of the passage ways inside the converter to melt shut. Eventually, so many are melted together that the converter is too clogged to let all the exhaust gases go through.
That's the main issue, but there are other causes of failure too.
