Because of the plug coincidence, I am beginning to suspect the IMRC because that is the only other thing I touched really. I moved it aside & turned it upside-down while I did the change.



I did the same, swapped out plugs again, the problem went away for 3 days, then returned. IMRC ? Please elaborate, I was thinking maybe bad plug wires. Have you made that change ? I just gotta think it's something in the ignition system. I had no stuttering, I changed plugs, had stuttering, changed plugs had no stuttering for a couple days, then it returned. But maybe as somehere who seems to be quite a bit more knowledgeable than I said, the new plugs just mask the problem. And I believe he's correct. But I have stock airbox, stock exhaust, the only mod I have engine wise is a Borla style, stainless steel muffler. So, yes, I am frustrated, if only our local Ford dealers cared about us (I mean other than when a sleazebag salesguy walks through the service area and says "my that's a pretty Tour, I have a list of people wanting to buy our good, used Tour trades. You probably are wanting to trade that old, used up Contour on a new Taurus wagon aren't ya" ?) Ken 99 SE
