my stereo forgets all, no memory, unless the memory power cord is hooked up.

I have never done that, but I will have to. I am still gonna try to reset the PCM so I can get my car back on the road, but then, clean it tonight. How long does it take, anyone know?

So i checked out your link TourDeForce, and went home, and attempted it, very simple to do. Still gotta little cleaning to do, and putting it back together. I just bought the gasket, and will be installing it within a hour or so. Excited to get my car back on the road. Also, the EGR Sensor, where is it as I might need to replace mine, and Well, the junk yard is the place to start for me. I don't mind paying $5.00 for a used one, if that even, the yard I go to is very reasonable about giving small things for a couple dollars if not free. Thats where I go to get my head light and fog light bulbs. lol.

BTW, all of those three holes, plus the one on the throttle body were completely clogged.

Auio,

The DPFE (Differential Pressure Feedback Electronic Sensor) is like under the TB bolted to the side of the engine. It has 2 hoses on the bettom of it to sense pressure (obviously) and an electric connector on the front surface.

They commonly go bad on our cars, i bet that is the problem. So far i've replaced one on my sis' 99 3.0 Duratec taurus, and my old 99 2.5 duratec stique. The old ones had a case made of metal and they were manuf. by kavlico i believe; the new one (which you want) has a case made of black plastic and its made by Motorolla. I say just buy one new, you don't want the old poorly designed ones which prematurely fail from a JY. Its easy to change, just scrape the old hoses off of the metal one because they're most likely melted on, then just swap.

The accordian tube and some other crap needs to be moved to gain access to the area.

Fwiw, i believe that ford used only one (or a small # of) DPFE sensors for the last few years, so if you get lucky, look for a black plastic one from the JY.

I will look in a few minutes, but I am still not sure where I am looking at lol.

Okay, i found it, but first, let me start with this:

I cleaned my Throttle body and the UIM. Wow what an amazing difference, after I cleaned it. Then my dad cleaned it even more, he found [censored] lurking in dark holes, and well got twice what I did, and it was already sparkling when I cleaned it. I bought a new gasket for 2.99 from napa. Returned to my house to put everything back together, reset the pcm, and drove for almost 2 hours. Nothing. So, I figured I would drive my car home, and then to the emissions station in the morning before I went up towards canada with my sis tomorrow. As I am driving, i miss the gear the the rpms sky rocket to about 6k. POW I see the Check Engine Light come on. How sucky is that. So tomorrow morning, I am going to go buy a new piece at the junk yard to replace that sensor you guys were talking about, hopefully this will solve my problem. Till tomorrow. Thanks everyone for the help.

Its nice to know the Differential Pressure Feedback Electronic (DPFE) Sensor, on the pre98s, had small bolts going through them, and on the post97 models, had larger bolts going through them (from the engine block). I just tried to install one from a 95, only to find out that well, it doesn't fit, time to go buy a drill and drill bits. this sucks!

So, I noticed some other things that are different. The harness for the sensor is different from the pre98, and post97. The post97 is larger and the pre98 is smaller, just like the holes. So I am gonna return it and say well, i couldn't even hook it up due to the different sized holes, and the connector is different. he said if I used it that He would only allow me to exchange. I will see if they have a different one that will fit. Otherwise, I will have to get one from the ford dealer tomorrow. Any clue on the costs.

Fordpartsonline says $70 for them, $85 list.

What i was saying earlier is look for DPFE sensors from other late model ford cars, specifically duratec taurus' from the last few years, i know they use the same exact sensors.

Now that you know what it looks like, you should be able to identify the correct one quickly.

Try to get teh plastic one....

I am gonna go look for a new one today. They didn't have any taurus unfornently.
