Thanks to all for your replies!

I've searched the forum for information on how to replace the EGR valve, and even went so far as to open the hood and look for the valve myself.

Just to be sure, this is it, right?



And to replace it, all I need to do is remove the two 8 mm bolts and wiring harness and drop the new valve in place? Is it really as simple as that? (Somehow I doubt that it is.) I haven't found a detailed procedure for removal, which tells me I am not searching for the right terms. I've read that using a stiff wire brush along with a strong vacuum to clean off any carbon deposits is recommended.

I've found Motorcraft EGR valves (Part Number CX-2056) for around $250 from Auto Parts Warehouse. Is this about the right price? Does this kit generally include a gasket, or does that need to be purchased separately?

Thanks for playing twenty questions with me. If anyone can point me in the right direction, I'd appreciate it!
