I realize this is a Ford Truck newsgroup, but I asked this in the alt.autos.ford group and got no helpful answer so thought I'd post here.
My Windstar has a cylinder 1 misfire (I had AutoZone scan the computer and that's what came back, along with a P1407 - EGR No Flow Detected code). I changed the plugs, but still have the misfire so I'm assuming it's probably a plug wire which I will also change if needed, but first wanted to ask if it's possible to check for a bad wire or possibly a bad coil block. I can remove wire #1 from the coil with the vehicle started and there is no change in the way it idles nor any sign of sparking (no spark sound and nothing visible). So....is there a way to test for a bad wire and/or coil? Also...what about the EGR code I gave.... is there something I can do myself to test and find out exactly what the problem is? Any help is gratefully appreciated as I really don't have the money to spend right now to take the van into a shop so if I can buy parts and fix it myself that would be great...
