Hi Clint, thank you so much for your video's, I changed all sensors and put in new harness and IDM still had rough idle ,watched your vid and fitted the 86Industries (Fischer Bro's) spring = Problem solved, it was a costly $$$$ diagnosis here in Australia as most of our parts people supply after market junk from another place I won't mention I rely on your video's and RiffRaff (Clay) shipping is a killer but worth it for Ford OEM parts. Kind regards from the Pilbara Western Australia. My truck is Aus spec 2005 S/Duty 7.3 made in Brazil and has done a lot of outback work. Stay safe.

For those wondering, you CAN get a brand new main engine harness still. Riff Raff Diesel sells them. You just have to send them your VIN so they can make sure they send you the correct harness. So no you don’t have to rebuild your old harness anymore.

@@hawkeye1776, i’ve been a master diesel tech for years as well. I never said anything about building an engine that will blow up at 100K. I know how to build a diesel engine. My 7.3L fuel system has already been fully upgraded minus a sump and FASS or Airdog fuel pump (which will be next). I have a fuel return kit already installed so there will be no “deadhead” issues with the fuel. And in reality the turbo for any year 7.3L is too small for the size of the engine. The Garrett GT38R or a turbo from KC turbos or Ryan’s diesel service are a drastic improvement over stock or even a factory housing with upgraded internals.

Early 1999 F250: I have a totally different surging. Engine is cold and surging 1,000 rpm’s every minute. On Forscan you can visually see the IPR build until it crashes at or around 40%. It smooths back out for a few seconds and surges again. It does this until the oil temp gets to 160 degrees and then I’m good. I still have the bucking in 1st & 2nd gears though. All New; Main Harness, Valve Cover Harnesses, Fuel Pump, Fuel Pressure at 62 with no drops in pressure, Ford ICP, IPR, every sensor has been changed out with Ford brand, High Voltage IDM, Stage 1 High Pressure Oil Pump, Hybrid 180cc 80% nozzle injectors, Gas Peddle, Transmission, Slave Cylinder & so much more. I have spent over $4,000 chasing this problem not counting Transmission, it had 423,000 miles on it and was tired. Problem started after 37,000 miles on rebuilt motor. I have videos of the Forscan numbers during operation showing IPR numbers. Truck has 53,000 miles on rebuilt engine and 423,000 over all. I’ve learned to live with it instead of keep throwing money at it, but would be nice to get it figured out.

After I swapped out the chinesium IPC, IPR and cam sensor, my truck started running great again. There are certain things in life that you can't save money on and that is those three items. Buy verified OEM only. Had to replace several connectors, but the wiring in the truck isn't too bad for a 99.5 model. I installed new Alliant injectors as well, because it still had original Ford installed injectors with 317k miles and cylinder #1 was not getting enough fuel. That cylinder was a dead miss, wasn't contributing. #6 and #8 seemed to run hotter than the rest, so just did all injectors and glow plugs at that point and now the truck starts/runs like a brand new diesel, thanks in great part to your videos. Love it. Also installed a Powerstroke 6.4 liter starter and now it cranks so fast you think it's at idle speed before it even lights off.

If I'm running around 1600rpm in high gear it bucks like a manual trans when you are driving to slow in too high a gear. This is with almost no throttle input at all. If it bucks, and I press the throttle down , it goes away.

I'll be at 4000 rpms going 45 easy and 2500rpms going 25 easy. Sometimes I'll turn it on and it shifts no problem other times I can't get it out of first other times it would shift past 3rd. I've had the od light flash when it's doing this but it's also done this with no od light flashing (quite often) and there are no codes to help put. I've changed the cpm, I've ran seafoam through the gas and engine oil to clean everything, I replaced the solenoid pack, I've replaced the actually od stick and that's where I'm at. Any ideas of what could be going on? Help would be amazing I'm about ready to light the truck on fire.

Very good info. Have some electric problems with a 7.3 early 99, April 15 1998 engine mfg date. Received a new engine wire harness which was incorrect for this engine, in process of correcting problem. Original symptoms were weak crank, check engine light stayed on about 2 minutes light goes off immediately rpm surge followed by irratic running of engine. As the engine warms it levels out andruns smoothly, however has a tendency to surge at low speeds. Also the alternator got quite hot quickly on starting ( had slight current feed back with key off in plug for wires) short in alt? brush dust at fields to armature? Will replace with new alternator. Checking harness for damage, hopefully can get the correct new one . Anyway, thanks for your invaluable information. Great video.

Thank you so much for taking the time to post all your videos. Can 1 bad injector cause the truck to run for a second then die? 02 powerstroke. Frustrated to the point of throwing parts at it. Parts thrown-new valve harness and under valve harness, new wire harness, new cps (ford), new ipr, new icm, new pcm. Everything ohms correctly at the icm plug. Even the #3 injector that is throwing po267 (low to high open) and p1273 (high to low open). New injector on the way, but would think the truck would still start and run with one bad injector. The wires look good where they cross over the valve cover. It starts right up, runs good for a second then very rough then dies. I can put my foot on the gas pedal when I start it and it will start, rev up, run rough then die. Tried unplugging the ICP same results. Fuel pump easily fills the bowl, but have not checked the pressure yet as the pump is newer. I really thought I was chasing a wiring-sensor-module problem. After reading back through this post I think it might be on the fuel side. Sorry this is so long. Any input would be greatly appreciated.

I didn't know much at the time so just replaced the cps. My icp was leaking and no difference when unplugged so I changed it and pigtail and now it does changed the idle but still lopes and had a more clattering sound when unplugged.

My ebp is unplugged because it was probably clogged causing the turbo hiss and low power in 60 degrees but no CEL.

I've pulled 20k lbs no problem. Anyway, the other night it started missing bad fairly bad. Lower power, the idle still idles the exact same, my duty cycle bounces around at idle and icp psi with it of course. My fuel filter was dark but who knows when it's been last changed. Truck had never lost much oil and it's had to been leaky given its oily underside. I drive this truck 100 miles a day 6 days a week and it's all I have. I've ordered an ipr but I don't know what would be causing the miss.
