My 04 f250 surges when at stop lights and even sometimes dies but then it starts right back up. I replaced the icp sensor and that fixed the problem for about a month then it started doing it all again. I unplugged the egr valve but still surging. It doesnt happen everytime I drive it, but it is really nerve racking one of these times I"m gunna rear end somebody when I'm not paying attention does anyone have any ideas.

if you have the time, an egr delete kit is a good way to go. prevent future issues. I have had the first coast diesel kit on mine for 40k miles.

Sorry to say, but my FICM died the day before our vacation last Saturday. Suging bad and then would die, start and then die. Bad surging like I was trying to a do a 4x4 boosted launch in 4x2 truck. :doh: Codes ran showed no communicaton with the FICM. Jody found that a cold solder joint in the FICM came loose. Soldered it back and it's new again. :bowfast:

I had it hooked up and the only code that came up was one for the egr so that would mean the valve is bad right??

I had p codes too, but they were non related to the FICM. Jody had to hook up a ford diagnostic software to find out there was no communication to the FICM.

I have replaced the icp, ebp sensors, and have egr valve delete on it and it is still acting up. i have heard that it could be the ipr anyone have any ideas on that.

Data log will show you. See what IPR duty cycle is when all this is happening. Matter of fact look at everything. Proof is in the pudding.

My truck was just in for the same issues, the dealer found it was the IPR and ICP were clogged up. Replaced them, and the truck runs fine now.

Update on the surging I just replaced the ipr and the icp for the second time worked great for a couple weeks and now it has started again so does that mean my next step is the hpop

Did you ever data log it while it was surging, or just throw some parts at it and hope for the best?
