with fly-by-wire, there is no iac, the computer can do the same thing since it actually controls the throattle plate via stepper motor.
But there is a MAF sensor that can be cleaned carefully. Vacuum leak is another possibility.

jims' right.

I *think* the break point was 2004. On earlier ones, it would be mounted where you'd expect on the tb. There are pictures in here somewhere...


Far as the coil, I couldn't find a specialty one in the same approx price range as stock. I even talked to accel about it. Well, I emailed them, and they promptly ignored me. (did you know accel and mallory appear to be the same people??)

Where'd you find that accel pack? (interested)

There should no IAC on an '04, do you have a cable going to the TB?
My V8 Fly-By wire is in the pic below. Just above the '4' of the 4.6 there is a motor.

No IAC on 04 4.0l

I just went thru this... took explorer to dealer, shop foreman owes me a coffee as he bet me there was an IAC .... went out to truck and with the new drive by wire system the IAC has been eliminated... They updated my pcm, I had just installed new plugs, air filter, cleaned MAF and installed new fuel filter. Truck is running much better. The fuel filter is a must if you dont know when the last time it was changed. Just my 2 cents... good luck

So....

what do think you wound up actually getting?

PS - I can't stand advanced. The last part I bought from them was wrong, they knew it was wrong, and a poorly painted reman at that. Bleah
