Lately I have been having problems loosing power. Truck wants to miss mostly going up hill and runs sluggish I'll pull off the road and let it idle for a minute and it will run fine. And it is only occasionally some days it don't happen at all and other days it happens quit often. New fuel filter, oil is good, had it on the scanner and isn't throwing any codes. Around 230k miles newer injectors.

Engine felt like it was running out fuel, injectors were clacking. I got home put on AE and it has a low high open on the code reading. took valve cover off and plug came out. I did the quarter modification.
Anyway took the truck out a few days later truck drove ok when cold then after about an hour it lost power again and started clacking until it died out. I had to stop and let it cool off about 10 times before i made it home. I changed ICP sensor. took it out for ride and about ten minutes later same thing. I have to let oil temp get down to 165 before i can drive it again.
When i first drive it Icp pressure is about 500 at idle and 2650 at full throttle, that is until it starts clacking again and losing power then the engine wont take any throttle..and ICP duty cycle is at 26%... Would bad IPR do this??
Ford 7.3L Power Stroke (1999-2003) :: Fast Steady Leak From The Fuel Rail Outlet Fitting While Running
I had just replaced my the fuel pressure regulator in the fuel bowl because it appeared to be leaking from where the FPR is, now with the new FPR , it is no longer leaking from there but now leaking (fast steady leak while running) from the fuel rail outlet fitting... How do you replace these, why all of the sudden it started leaking there ???

I have a 2002 7.3l with 229k miles. So I am having a big problem now missing oil! My reservoir is empty and my dip stick is reading low, and i just put 16 quarts in yesterday with the new filter! im having a long start issue obviously because i don't have any oil supply! just drove the truck today, ran great been having this issue for the past week. here are the details. i came up from Texas after installing joeys t500 pump, when i arrived to California there was oil everywhere! my pump that joey rebuilt had an issue so he sent me another and bam! runs great no probs, now after about to weeks and about 15 degree temp drop i get hard starting. first time instead of a 2 second start up it took 9 seconds, now it takes anywhere from 9-20 seconds to start! so after my drive today i let it sit for about 3 hours seeing if maybe i had air in the lines from the res not being full, well now i cant get a start at all my res is empty and my dipstick shows little oil, i just replaced the icp. ipr, and eot when i put the first pump in, could this be the lpop?

I have been having a problem for a while now where my truck will miss/buck at WOT. This only happens at higher RPM's. From a standing start 0-60 it is fine. However when I downshift full throttle from about 50 MPH it initially goes, but then it will miss/buck consistently until I back off the throttle.
I have so far replaced the CPS, re torqued injectors, checked valve cover harnesses and fuel pressure stays in between 64-58 full throttle. No codes show up.
My truck runs great except as I described above. I would think an injector or two are bad, but the truck runs and idles great. My initial guess was that it was a fuel pressure issue, but fuel pressure holds strong. Could it be air in the fuel?
Ford 7.3L Power Stroke (1999-2003) :: Intermittently Missing While Idling / Driving?
I have a 99 f450 with a 7.3. Here lately it has been "missing" when driving or idling, but only every now and then. When driving down the road it will start bucking and boiling black smoke out then the ses light will come on and like turning a switch everything clears up and it acts and drives normal.

I have a 2001 7.3 that almost has everything practically brand new... new hpop, water pump, uvch, gpr, glow plugs, icp sensor, ipr sensor, cps and new turbo pedestal that was leaking oil, well now my truck has a cold start to where it has to be plugged in to start and when it finally does it smokes white pretty bad, misses and sounds like it's jumping around under the hood up until it warms up and revs fine with less white smoke but still a miss!!
Compression on test has been done, and good, fuel pressure is good, but the buzz test when cold shows 123457 muffled and quite and when the truck is warm only 3 and 4 are still muffled and quite? Injectors sticking?? Or just need New injectors!
Ford 7.3L Power Stroke (1999-2003) :: 2001 - Cylinder Missing Until Motor Warms Up
My feed truck (2001 ext cab 4x4 7.3 198k) had a cold starting issue I fixed with new gp relay. Now I noticed when it gets down below 30 degrees it has a cylinder miss until motor warms up. I don't doubt injectors are in my future. I was wondering though if that is common for worn injectors or if maybe something else has gone haywire and how long can I run it like that before something else tears up? after about 7-10 min the miss goes away and I don't notice it. I would like to get through the winter before messing with it or having injectors put in it...

My truck was shuddering in od. So as I last effort thinking it might be injectors I pulled all of them and replaced all of the orings and valve cover harnesses. After all of this was done seemed to do nothing at all. Now a new problem has surfaced. It's having idle problems. It will now idle at 780-850 instead of 650-700rmps. Also on deceleration it will miss pretty bad. Checked all of my injectors again all connections are good and all of the injectors are tight. Not burning any oil. So I unplugged the icp and bam runs like a top perfect running engine. So I bought a new one and plugged it in and itake doing the same thing. So what is going on! Also it was throwing a random check engine light but wouldn't bring a code up I'm completely lost....

I purchased a 2000 7.3 dually 4x4 and the driver side battery is missing with the cables snipped.
I noticed the headlights do not function, neither do the brights, the air does not blow. Is this related to the missing battery? Someone said they are on same circuit and dont do separate tasks.
Still starts runs drives fine...
Ford 7.3L Power Stroke (1999-2003) :: F250 Missing And Smoking A Lot / Light Blue Almost White
Just picked up a 99 F250 7.3 Stroker, it had sat for two years in a warehouse, the truck had just had reman injectors put in right before it was parked. We fired it up, and it was missing, and smoking a lot (light blue, almost white) I checked the oil filler cap, and no water on it, after it ran for a while, it stopped. Shut it down, went and got my trailer ready to load the truck, fired it up, and no smoke to speak of, by the time I got it to my trailer, still no smoke.
I revved it against the governor a few times, hoping to clear the miss (figured may have been trash, or a sticky injector from sitting so long) It is turned up pretty good, as it came with a Superchip Super Tuner. It seems to hit on all eight above 2500 RPM or so. Brought it home, and took it out on the road, it seems to only miss under 2500 RPM or so. I took of from a dead stop, then got on it hard at about 15 to 20 MPH, it took of nice, then all of a sudden, the tach started climbing like the trans was slipping, looked in the mirror, and the tires were smoking, guess they broke loose when the boost came in!
I let it idle and warm up for a good half hour and noticed a lot of pure white smoke coming from the exhaust, went back to it and it was steam, I took the oil filler cap off, and there was a lot of steam coming out of there, pulled the dipstick, more steam, I then noticed the degas bottle was low, I topped it off, and got in the truck, and revved it a few times, then held it at 2500 RPM for about a minute, It started blowing water out from under the degas bottle cap. I called the guy I got it from, and he did NOT put new injector sleeves in when he did the injectors, I don't see any oil in the water, but there is water getting on the oil filler cap now! Does it sound like a head gasket, or an injector sleeve?
Ford 7.3L Power Stroke (1999-2003) :: F250 - Missing And Jerking - Code P0541 / P0640
1999 F250 7.3 .. The truck seems to idle fine and and runs smooth all the way up top cruising speed, but when it levels out at say 65mph then it starts missing and jumping. I can ease into the throttle a little and it smooths out up until it levels out again.
I have the Vgate Elm and Car Guage Pro and a couple of other apps and the only DTCs I'm getting anymore are:
P0541 Intake Air Heater Circuit Low
P0640 Intake Air Heater Control Circuit
But from what I've read, neither of those should cause this issue.
Buzz test sounds good.
Cylinder Contribution test throws code for #4 Cylinder
I'm trying to do everything possible before throwing an injector in it.
Ford 7.3L Power Stroke (1999-2003) :: F250 - EBPS Tube Missing - Important Sensor?
I have a '99 F250 SD 7.3 & im going on a trip next weekend so I thought I'd pull the exhaust pressure sensor & clean the tube in an attempt to get better mileage. Found the sensor & unplugged it. Went to the manifold & started removing the tube when it fell off. 6" from the manifold it's broke & the rest is completely missing.
Autozone doesn't carry this tube so, how important is this sensor?
Ford 7.3L Power Stroke (1999-2003) :: 2001 F350 - Missing And Shimmy - RPMs Will Drop A Little
I ran out and test drove a new to me 2001 F350 7.3L tonight. Everything seemed good, until I got back from the test drive. I pulled in and was sitting there with it idling. It seemed to idle fine, then a very small miss and very small shimmy then idle fine again; then another small miss and another shimmy. It continued like clockwork. Every time it seemed to miss and shimmy, the RPM would drop just a little, but not much. Does an ICP sensor sound like the problem, or maybe something more serious? 2001 F350 7.3L with 235,733 miles new trans, turbo replaced at 150,000 something miles. No blow by. Idled fine before driving, also drove fine. It doesn't seem to surge when idling, just kind stalls and shimmys for a split second then idles fine for a few seconds.
View 1 RepliesFord 7.3L Power Stroke (1999-2003) :: F350 - No Crank - Anti Theft Plug Was Missing
I have looked through a ton of threads to see if I can find one similar to my problem but have not. I have stock setup but had a dealer installed anti-theft device. The first time it would not crank, it was like the the anti-theft plug was missing so I checked out the key, tried the spare and finally removed it all together. I checked all the fuses and swapped the Starter relay for another of the same part number.
I later sifted it into neutral assuming it was the P/N Switch and it started. This continued intermittent for several days but then Neutral wouldn't work. I got under the truck and pushed on the actuator rod for the transmission and it started again for a few days. If finally failed again and I had time to buy a replacement switch.
Once installed I verified I had back up lights in reverse but still no crank. I have since pulled off the starter and had it verified as good. Is there more to setting/adjusting the neutral switch or is there something I am missing before I tow it in?
Ford 7.3L Power Stroke (1999-2003) :: Ran Out Of Fuel With 1/8 Tank And No Low Fuel Light?
So my 7.3 started sputtering and lost power, died on the side of the road. I wasn't far from home put about 8 gallon of diesel in the tank with a couple of fuel jugs and it fired right up.
Gauge was reading 1/8 of a tank and low fuel light did not come on. (low fuel light comes on when you start) Gauge came up to about 1/2 after putting fuel in.
What happened? Gauge was always reliable and low fuel light always did work. Only work done to fuel system was had new tank straps put on a couple of months ago.
