Hesitating/Surging issues.

Talking to my buddy he told me to buy the IPR "rebuild" kit and he would do it for me. His Excursion was totaled in an accident so I let him take the truck tonight until he gets something else. So I ordered it tonight. We'll see if that fixes it. Worst case scenario is it doesn't change anything and I'm only out 30 bucks.

Ok.. update..
I got the rebuild kit.. Got the UVCH shims.. Oil and filter...
About a month ago I changed the oil when I was doing the caliper pins, but never got to the Shims or the rebuild kit.
Odly enough it seems the jerking and surging has gone away.. I've been very hesitant to post this because I didn't know if it was a temporary thing or not..
I'm not calling it "fixed" or "solved" but just wanted to give an update on the situation.. We'll see how things are in a month or so.

I have a 1997 F350 that has the same surging issue at low throttle. It runs great if I mash the throttle, or it up to temp. Last fall I also had an occasion where I turned the corner and pushed the accelerator with no response. I replaced the TPS and it seemed to improve the overall driveability. I don't know if I would say it was completely gone but now it seems to be acting up once again. Mine has been going on for most of March. I feel your frustration!!!! I too am going to subscribe for any updates. If I figure anything out I will post.

Subscribing. My 2001 7.3 F250 is doing all of this.

Power loss (bogging down) when I mash the throttle down while it is very cold (although it stopped doing this after the weather warmed up here. It only seemed to do it when the truck and the outside air temps were very cold). It would idle just fine. But as soon as put my foot in it, it would act like it wanted to die. Once it warmed up after 2-3 minutes, it ran ok.
Overdrive light flashing periodically when this was happening. But sometimes it flashes even now even after the first symptom stopped happening (since the weather warmed up). It still has the periodic overdrive flashing light now.
Surging idle when I put it in park.

and I thought I was dumping money into my truck! Just installed the fuel pressure gauge, rear calipers, pads, shoes, changed rear axle fluid, changed rear cover (upgrade), fixed the thermostat housing leak, recently replaced the ICP, replaced 4 glow plugs and just ordered a trannie filtration kit and am going to change the trannie fluid since I know it's on it's last legs but I don't have the $$ for a new or rebuilt 6spd atm.
Even bought a fuel pump with plans to drop the fuel tank and do all the tank mods and replace the pump until I found that I was getting 72psi and maintaining 62+ at WOT.
Anyhow, let us know how it goes and if rebuilding the IPR helps, it is next on my list and I'm thinking I may grab a TPS as well since I'm starting to get a little shutter here and there, specially when it's cold.

Well Sorry for not updating this post..
Odly enough I stumbled across it in a search I was doing for something else.
3-16-11 I posted that I changed the oil and it seemed to fix it. I drove around for about 4,000 "ish" miles and it started to surge and hesitate again.. So I changed the oil and it went away.. So I'm going to go with the assumption that it's just because of old oil.
I don't put many miles on the truck a year.. Maybe enough to warrant 1 oil change..

I forgot about this thread but just got a notification of a new post. I fixed my trucks and it has been fine all winter. I had a clogged EBP tube. My sensor was so full of soot so I tried to clean it but it made no difference so I replaced the sensor. It still didn't solve the problem. I took my pedal assembly off and checked both my TPS and IVS. I had replaced my TPS one year earlier with an after market one. I could see the meter jump/bounce around when checking the IVS. It was very hard to see and only happened just as a pushed the pedal off idle. (right where the problem was) So I broke down and bought a new Ford pedal assembly and it totally fixed it. Hope this helps others

I thought I'd give a long term update on mine. The battery replacement didn't cure the problem but an alternator did. I've had no more issues at all since the alternator was replaced. Turns out that my alternator was putting out plenty of voltage, but it was showing anomalies when the mechanic had it hooked to an oscilloscope. Something about the diodes that was putting out uneven power that was wreaking havoc on the various electrical systems on start up. Caused some sensors to read incorrectly among other things. All's well since and it's been about a year now.
