It should be throwing a SES light.

I'm going to start off with the basics, even though @ this point it's probably unlikely, but have you had your Cam Position Module(CPM) replaced?

The throttle position sensor will likely work correctly, or not work at all - as it is a resistor type device - like on track-cars.

Cam position sensor, is another good idea to check - or replace. The price varies widely from $20 - 200.

I ran an air filter too long - and it threw things off, as it got clogged.

$200 for a CPM?????? In all due respect, where have you seen a CPM that goes for $200, besides dfuser.com's IH Blue for $135? The IH grey & Ford grey are the same, but IH's is usually cheaper. The most I've seen for one from Ford dealerships in other states is $35.

So I overdid-it a little, but the damn sensor was $186 - here in Santa Fe, NM - when I asked.

Taxes and all - that's $200.

One year later they charge $30-some for the same part.

They may slap us extra for 'high altitude' here, what do I know.
I asked about the reduction in price, and they told me 'Ford had gotten a new vendor'


They wanted about the same for a fuel pressure sensor, which I stupidly bought, just to find - it wasn't my problem.

I don't buy parts much from my local dealer anymore.

Sorry to hear that, man. Sounds like your Ford parts dealer is trying to make a buck or 2, eh? Ford & IH have been outsourcing most of their parts to a factory in Mexico for sometime(henst the big recall on the CPMs from a faulty diode that saved 'em a buck). Try autopartswarehouse.com if you need Powerstroke OE parts. You might have to wait a couple of days for delivery, but it sure beats Ford dealer's trying to suck the blood out of you. By the way, welcome to the .org if no one else has said it to ya!
