Where did you find the EGR for $50? I have been searching and I can't find one that cheap, I would love to though. Can you send me the link. Thanks

I've got the same problem. I did have the P401 code flash. Found the part on amazon using the motorcraft pn from rockauto. cheap about $75. That didn't fully fix the issue but I've noticed that since it has gotten colder it doesn't happen as much but still does. Any progress? Has anyone had this issue and a transaxle change fixed the problem?

I should have been clearer on my problem. i have the same issue with my van jerking at 45 mph under load in 4th gear at low rpms before upshifting.
I also have the driver seat heated seats not working. I see both problems in these posts. Has anyone actually fixed either?

Had the same problem.....replaced the EGR valve, replaced the coil and wires and spark plugs, no real difference.
I now believe that moisture got into the PCM connector and once it dried out, the problem went away...see this link for a detailed description (its a pdf doc.)

I agree, we need to get together and fight Ford. The problem is I'm in Canada so we don't have the same laws...

I had the same problem. It would jerk at around 45 mph. I took it in, and there was a cracked vacuum hose plastic part thing, and they replaced a coil head and spark plugs. it all came to around $1200 with labor at a Ford dealership. Since I know nothing about cars, I had to pay it. It did make the jerking go away.
I just feel the van isn't running smooth. The idle sound is so loud, like a truck.
My driver side heated seat also died. When under warranty. They "couldn't" fix it, or so they said.
I'm at 91000, and I hope to be able to drive a few more years. I'm still paying on it! blech!

I am experiencing similar problems, Jerking under load at about 40mph. The CIL came on after. Diagnosis revealed the above codes. What is the easiest way to get to the No. 1 cyl. and what could be the possible cause for a misfire.

Not sure what is going on with my Monterey. It is a well cared for 2004 that all of a sudden started to have a little shake when accelerating. Once I got up past 50-55ish it almost went away. I assumed I had a wheel out of balance so when I had it in for an oil change a few days later, I had them do a rotation and balance. That really didn't fix anything and it got worse. If I was accelerating up hill(which I have to do a lot since I live at the bottom of a hill) then it was like I was driving over hundreds of broomsticks that someone had lay across the road. I took it to a shop (not my usual one, but it was very close to home) to see what they thought. They looked and said CV shaft. When I was able to get it into my regular shop, they looked at it and said 'Found transaxle output shaft bearing on right side axle very loose causing excessive movement with right axle.' He said the right axle was basically loose where it attached to the transmission. They said they would have to research if it was actually a bushing or a bearing in order to tell me the repair cost. Monday morning I get a call saying basically I need a new transmission. Now the vibration isn't as bad, but is still there. It also feels like it is wanting to take off while I am driving at a constant speed. Not chugging out, but like all of a sudden it gets a little burst of more power then stops. After seeing all of these posts, I am a bit worried since I have five kids that I haul around in this thing. It just hit 125K miles.

After having my van in the shop for a final look over before my extended warranty expired they diagnosed and determined that the spark plugs needed replaced. Between that and recalibrating the timing my issue was fixed.
