Ford 7.3L Power Stroke (1999-2003) :: Truck Constantly Bucked And Would Barely Reach 20 MPH
Dec 18, 2015
So I have had this occasional hiccup that has gotten more frequent. I figured since our weather has been extra cold (lows about 15 F, around 22 F in the morning), that the temperature had been contributing to the issue. My truck would hiccup and burp out some white smoke. At first it didn't throw a check engine or any codes. As of recently I would get a check engine light, but torque pro could not get any codes, they would be cleared when I cycled the key. Anyways, I finally got some codes yesterday because it happened again. The codes where P0603 and P0344.
So I ordered 2 new CPS from Riffraff yesterday (hoping that they will be here today so I can install one). Fast forward to this morning and i get the hiccup again except worse. Now my truck would barely reach 20mph and it constantly bucked. I limped my way to work (only 4 miles) and of course I got a check engine light but there were no codes that I could retrieve with Torque Pro again. I had read on another thread that the guy had an issue with a wire in the harness near the 42pin connector for the IDM. He replaced his CPS taped up the wire and it went away.
I'm at work and now I'm paranoid that I wont be able to make it home. Is there anything temporary I can do for the CPS, like maybe disconnect it and spray it with some contact cleaner, until I can replace it? I'm going to trace the wire harness to make sure there aren't any bare wires. I forgot to mention that the local stealership replaced the CPS for free due to recall less than 3000 miles ago...

This is a 1999 with 200k on it. It has a really bad hpop so valley is full of oil. Haven't removed the HPOP to inspect the non serviceable plug or the hpop gasket. doing that this week. This truck I just bought and it has aftermarket injectors so dont know the miles in injectors. once the oil leak is resolved I can then give the injectors the once over to make sure theyre okay. Question is how much of a stream of oil should I expect to see as the engine runs?

My 2001 7.3 is smoking only when barely on the gas. New fuel filter. Don't know if its possible injector going bad or what? Smoke is white not black.

My right front window would barely move when I was opening it. Binding real bad on the way down. So I pulled the door panel, ( a two minute affair ) lubed all the tracks with silicone grease. Now the window goes down very easily.
I had all four doors done in an hour. To remove the door panels, remove the red reflector from the door, remove the screw underneath of it. Gently pry up on the window switch bezel at the front for the front door, and the side for the rear doors if so equipped. There will be another screw underneath. Unplug the switch, remove the screw. Remove the trip piece from above the hinge area. Push up on the panel and it comes off.
I used that real thick silicone grease that you can get a plumbers supply for lubing faucet o-rings. It looks like double thick vaseline. Windows work like a dream now.

My 6.0 with 178k on it just started to have issues today. Low power. When I hit the pedal hard the motor revs and the truck barley moves. When I baby it it goes up to speed and shifts fine. Overall lacking power and not going anywhere. No CEL on. Turbo spools and seems to be ok.

2001 Ford Excursion 7.3 will run barely for about 20 sec. shudders, then dies. Bought new, driven 334K miles. Performed the usual fixes common to 7.3 issues over the years. All original injectors except for #7 which I replaced about 5 yrs ago. (I know should have replaced in sets but not in the budget at the time). Anyway had my wife turn the engine over after I had removed valve covers for inspection and observed a lot of smoke coming out of what appears to be at or around number 7 rocker arm valley? All rocker arm/pushrods look to be moving as they should beyond that I'm in over my head. Am I screwed or could it possibly just be a bad injector/injectors?

My vacuum pump I noticed is running constantly and also my vents are stuck on defrost.
I narrowed it down by taking off the lines going from the tank to the 4x4 solenoid and the tank to the HVAC line. If I plug both lines I get pressure to both but it still won't shut the pump off. Why won't the pump shut off? Leaky tank?
If I plug the red line back into the solenoid I cannot get pressure to come out of the HVAC line. (Switch in cab set in 2wd)
I can make the pump shut off by plugging the main inlet to the pump.
I took the tank out and can't find any cracks or leaks. Could something inside the tank be broke?
Also why can't I get pressure when the red line is plugged into the selinoid?
I can't figure it out. Almost seems like the 4x4 solenoid and the tank are both the problem.

Had a weird issue come up this weekend. I went to drive my truck for the first time in a couple of weeks and when I got in I noticed a constant clicking from under the dash (whether the truck was on, off or if the indicators / hazard lights were on or off). I investigated and found it was my flasher relay. I have replaced this relay recently (within the past year) to an EP27L to accommodate the LED lighting I installed throughout the truck (hyper flash on the old relay doesn't even describe it properly, it was a constant buzz!) and it has been working perfectly until this point.
I thought it may just be something going on with the relay so I pulled it and replaced with the old EP27 unit I still had. It does the same thing, albeit at a slower rate (every 4-5 seconds). The lights do not blink when it is doing this, but still operate normally when I move my stalk up or down or when I press the hazard / flasher button on top of the steering column.
I am wondering if there is a short somewhere in my multifunction switch that is causing this issue? If so, why would it come up when truck has been sat? I didn't have the time, not the inclination to roll around inside my truck (hotter than hades here in Florida right now) to troubleshoot any further. I pulled the relay altogether until I get some time and cooler weather to look into it further. Otherwise the truck seems to operate as normal, even all the lighting seems to have no ill effects from this?

So from what I have gathered online, it is an injector(s) issue. I've only had it happen to me twice at that speed but when I came to a stop afterward, my truck was barely idling.
I'm not sure if my sct programmer is able to show injector codes but it will show gp codes. I guess my question is are failing injectors that intermittent typically? Also, much luck with Rev X clearing that issue up?

The brief information:
1. Stuck/non moving in traffic on the freeway for roughly 1 1/2. During that time the AC was running, but once I noticed my "battery light" on the dash turn on, I turned everything off.
2. Since then while on my way home from work the voltage meter only showed barely 12 volts at full throttle.
3. I charged my battteries, and started it up today to go into work. While going to work the voltage meter showed 14 at its high point, but shortly there after it dropped back down to 12. At which time the battery light came back on.
New battery or alternator?

I have a 2006 F250 6.0 Amarillo Edition. 133,000 When I bought the truck it was a theft recovery vehicle where the turbo, injectors, FICM and wiring harness were stolen. The company I bought it from replaced the injectors, wiring harness-new, and a used FICM, and turbo. Also has EGR delete and SCT tuner with basic tunes. I believe the SCT was put on to mask another problem. No dealer would spend that kind of money to sell a truck unless something was wrong. The truck would accelerate some with the tuner but shift the tires so hard it would bark them. I removed the tuner and went back to stock program.
The truck will barely move and takes a long time to accelerate under a load. In park and neutral it is fine. A friend has a ford diagnostic program on his computer and says the readings were all good except EBP was a little high. Removed exhaust and air intake to verify no restrictions. Turbo sounded like the vanes might be sticking so I replaced the turbo and VGT solenoid. Now truck feels like its trying to make more boost but not transferring power to the engine. Have blown the silicone hose off twice now during testing. Checked the EBP sensor and tube and only thing I see is a little carbon buildup inside the sensor. What else to check. I'm new when it comes to diesels.

I have a little problem with my 1999 f250 7.3 power stroke diesel. Every once in awhile, while driving the truck would die completely but i switch it into neutral and started right up. What could be the problem?

My 04 PS was blowin white smoke constantly while running. I just towed a uHaul from Connecticut to Virginia Beach and had some coolant issues on the drive down (I was out of coolant on 95 in PA, added coolant and it made the rest of the drive no problem). I got here to Virginia and it was low on coolant again. I added coolant to it, and now I have some other issues. I had what looked like oil comin out the stacks onto the bed, so I pulled the turbo thinking it was seals. But the turbo was just rebuilt prior to me buying it with a wicked wheel in it. It still had stock EGR and it has 202K on it.
Checked and found EGR valve was wet. Ordered an EGR delete kit, and just finished installing it. Now with everything put back together, the truck doesn't want to start. It cranks but doesn't fire. I pulled the codes from my tuner and I got: P0403, P0405, P0683, and P2623. I know P0403 and P0405 are related to EGR but the others I'm at a loss on. The EGR delete kit I bought included the blank to remove the valve but what do I do with the plug that used to plug into it? Any way forward to get the truck back up and runnin again? This is my daily driver and not lookin to break the bank to get it goin again but I really need her to be reliable.

I have a 2003 7.3. Suddenly a week ago when I left work, I noticed my truck wasn't picking up much, but i was in a 40mph zone. I then jumped on the freeway and noticed the truck would not go over 60mph. Once I exited and got on another road with a 55mph speed limit, the truck would not go over 45mph, I had the pedal pressed all the way down and would not go over 2000 rpms. Also, for the transmission to shift, I would have to let off the accelerator.

I have a e99 f350 7.3 all stock. I have no power. The truck will crank for about 15-20sec before it'll turn over. I just purchased the*AE*but am fairly new to understanding it all. In idle its a little rough and when I drive I can only stay in the neighborhood because of fear of getting rearended due to very slow acceleration. Whats weird is that when i have no power while i am driving ill keep the pedal down throw it in nuetral and my rpms and*icp*pressure jump up right away. Things I've replaced:
Icp*sensor
Fuel pump
Pcm
Tps
Cps
Ipr
Dropped tanked and cleaned screens
When cranking my*icp*pressure climbs slowly to right under 500. I dont know what else to do ive been working on this truck dor two months some days 13hs straight, I am feeling defeated. Codes p1249 1211 1209....

2002 f250 7.3l diesel...
I got a new radiator and the tranny fluid was the worst the mechanic had ever seen. He serviced it and warned me that it might not be long for this world. I broke my flexplate and so I had to pull the tranny, and I decided to throw a new torque converter in because it was giving g me symptoms like a broken sprag( it wouldn't rev up or do a brake stand in gear, therefore slow takeoffs).
I was recommended to replace the tranny, I decided I could do the job again down the road if I needed to. About two thousand miles down the road I had a hard shift going from overdrive down to get up a hill and about 10 miles later the truck started slowing down....I couldn't give it enough pedal to keep it going and the engine sounded rough.
I pulled over and checked fluids and everything was fine, truck idled fine, bright red tranny fluid not burnt at all. Pulled on to the road again and it pulled fine until about 40 mph and it wouldn't go any faster. I got it towed home and ordered up a tranny from Ford figuring it must be toast, but I thought I'd throw it out to the forum to see if there is any other troubleshooting I can do before I install the new one in case it is some other problem or some electrical harness or something, or if that is a pretty standard reaction to a fried tranny.
Engine runs good at idle, shifts perfectly to drive and reverse, drives forward and back(I'm very hesitant to drive it out of the driveway in case I can't get it back in). Only happened two times before I decided to tow it. Temps looked fine on the gauges, fluid was a little overfilled in the tranny, but again, not hot or burnt.

Problem started 2 days ago, driving around and my truck would stumble and lose power. Give it gas, won't rev up but it cleared and ran fine for a mile or so then it comes back (off and on all the way home). Check engine light didn't come on the first few times, came on a couple times on the way home (maybe 4 mile trip) but goes off when the truck runs fine. Thinking it was maybe the fuel pump (got 140K on the stocker). Talked to a few friends, some thought it was algae build up in the tank that was clogging the filter on the pump, underhood filter changed a couple hundred miles ago. Looked fine with slight brown build up at bottom of bowl when I replaced it.
Ran it around yesterday with a friend of mine and his scan tool hooked up, acted up once, check engine came on for a few seconds and shutoff. No code and for some reason we couldn't get it to live data while driving. I dumped in an algae eater yesterday and left the truck overnight since I had to work. Got home this morning to run her around the block to circulate the eater. Truck started and idled fine, went to pull out and she won't rev up, pumped the gas and NOTHING! Check engine light is on now but don't have a scan tool handy to read it. I heard the truck will store the code?
What this problem might be? What's a good scan tool for our trucks that can live data as well? CPS is good and already did the UVCH mod.

Well I have had a completely dependable truck until today. I was driving my truck on the way home, its an FX4 with only 33K miles on it that i have had since new. I went to accelerate to pass some cyclists (not a hard acceleration) and the vehicle cut off seemed like it kind of bucked a little as if it was shifting gears hard. I got a service light but what was weird was the gauges worked and the RPM still showed 1000. I did have power still though as the radio was on. The only thing that is currently wrong with the vehicle is the odometer gauge is out and needs to be replaced.
Anyway I shifted to neutral and restarted on the fly and than shifted back into drive and it drove the rest of the way home fine. After i got it to my neighborhood i ran it hard and it did not cut off again. I do not want this vehicle to cut out of me in town in the middle of traffic or while i am driving my 18 month old around and i get disabled with her in the truck. Slug of water maybe? I filled up on monday and still have around 3/4 of a tank of gas. Maybe short because of the gauge issue getting worse? I have the crazy door locks and beeps but nothing else has occurred. 05 F150 FX4 5.4 ....

My truck runs very rough and lacks power when cold, even during the Texas summer. Once it warms-up, everything is fine. It's almost like turning on a light switch. If it's plugged in for a couple/few hours, it's smooth as soon as it starts. I'm assuming it likes the oil once it reaches a specific temperature. What my problem is?

I want test my fuel pressure. What is a good gauge or kit to buy? My truck has lost power towing and is now starting to miss a little. I'm wandering if i my problem is in the tank. Is there a good scan tool that would diagnose things too?

So long story short I have a 99 f250 xl, 7.3 130k. Overall good truck but has no options, never had AC but would like to add it. I have seen the kits on bought4less. So I'm thinking all the factory parts should be bolt on, since the holes should be all there, and since most of the wiring should be there. I just need to collect all the parts. Also one question I have is, what goes through the firewall. Is it just the lines, or how does the ac get to the vents? Dumb question but don't get that part of it.
