Hey, I had a quick question, is our EGR valve just hooked up to the manifold and vacum line?? I waas thinking about removing it but I wanted to ask first if anyone else did to see if un-expected problems like a check engine light or a bad idle would occur. That way I can sell the new one that the previous owner gave to me with the car instead of using this crappy old one.

Yes, you get a CE light.

RE: removing EGR valve
The Mark EGR valve is connected to the exhaust and the intake under the throttle body "somewhere". There also is a flow sensor that measures the flow of the exhaust through the EGR valve. If the flow measured disagrees with what the computer ordered, you will get a CE light.
When I got the EGR CE light, it turned out to be that the passages at the base of the throttle body needed cleaning. This is a very common problem with these engines and other Ford V8 engines. Cleaning the passages and replacing the flow sensor was what the dealer mechanic did to fix my problem. The EGR valve was okay.

RE: removing EGR valve
well, will a seafoam run cure that "dirty" passage syndrome? Probably jsut run the typical seafoam routine then accelerate and release the throttel quick so it's a large pressure drop and works the EGR good so it can run through there and clean it up. How much does a flow sensor run ya?? hopeuflly it's not one of those annoying parts that you need a torch to get the bolts off.

No, but getting to the EGR is tricky. Lot of stuff you have to take off first.
As for the Seafoam, I'm not sure if enough of it can be sucked in to the EGR to do any good, or if it is strong enough to remove the thick deposits likely to be found in there. But it is definitely worth a shot.
