Ford 7.3L Power Stroke (1999-2003) :: Growl Noise In Front End Comes And Goes
Been trying to track down a noise in the front end. Got a growl and what sounds like a big cat scratching its nails on a metal plate. The metal sound comes and goes, but the growl is always present at one level or another. It sounded like it was coming from the driver's side. I jacked the truck and checked everything on that side and it seemed tight. It was all replaced about two years ago. I then started looking around and found the sway bar links were shot along with the bushings. I then jacked up the passenger's side and checked that.
Should have done this first as it was pulling to the right and not the left. The wheel was hard to rotate and stopped rotating as soon as I stopped forcing it. It was making a growling noise, but not nearly as loud as when the truck was rolling down the road. It also had a bit of play that I tracked down to the hub assembly. The ball joints and u-joints were tight with no play at all. The dust seal that should be on the axle was gone and the hub seal looked beat. Tie rod ends all seemed good. Ordering part now. My question is there anything else I should look at?
Ford 7.3L Power Stroke (1999-2003) :: 2002 - CEL - Rough Idle - Loss Of Power?
I have a 2002 F-250 7.3, 159k on it. I bought it in March, ran AWESOME up till now. I was driving to work last week, check engine light came on, truck lost power and started idling rough. I have a buddy who works for a Ford dealer as a diesel mechanic, he came over with his scanner and laptop. #2,#4,#8 cylinders kept coming up saying possible problems are injectors, harness, rings.. He also did an electrical check, that all checked out. He told me to get injectors, so I got 4 injectors (yes I got the correct #8 injector), valve cover gasket, injector harness and 4 glow plugs.
The parts came last Friday, we did the job and it ran great. Drove it Friday night, Saturday, Sunday morning, no issues. Sunday afternoon we were on our way to a birthday party, truck started doing the exact same thing... Check engine light, rough idle, loss of power. After I got home from the party, my buddy came back over, put it on the scanner again, getting the same codes again. Deleted the codes, ran the tests again, same codes, deleted the codes, rant the tests again, same codes.
He said he is going to come by tomorrow with the box to check each individual cylinder.
Ford 7.3L Power Stroke (1999-2003) :: 2002 - Idle Speed Goes Up
Truck (02' , 7.3 ) has check engine light and since I'm on vacation don't have access to my Autoenginuity diagnostic software, so looks like I'll have to go a auto parts outlet to get the code read.
But.... before I do I wanted to get some input from y'all. Basically what happens is the idle goes up while in gear and when I put it in neutral, idle goes back down to normal. In addition I noticed (yesterday) somewhat of a lope or stumble at idle while in gear. No stalling and no effect to fuel mileage.
Since I'm away and away from my tools I'm somewhat limited. Certainly once I get the code I'll know more.
Ford 7.3L Power Stroke (1999-2003) :: 2002 F350 - Rough Idle / Lack Of Power
I have a 2002 F350 4wd with the 7.3. I was driving the truck and all of a sudden it was running like crap. the engine light was on. after a minute or so the engine light goes off and the truck is running fine. then again starts running like crap. I am close to the house so I limp it home. runs like crap.... will barley climb small hills. engine light is on. get home turn it off... next day... starts up and runs great for 10 - 15 min. engine light comes back on... runs like crap.... my neighbor says "It's the crank position sensor" I replace it.... runs great for a month.... now it's doing the same thing......

I bought this truck a few months ago. After trying everything under the sun to try and rectify a poor running problem, it was realized that injectors needed replacing. Ended up putting in 160cc/30% unlimited diesel performance injectors. The truck has a rough idle and surging problem. After trying to install the chip from gearhead, the truck didn't run any different, ultimately (according to the shop doing the install) smoking the ECU. New stock ECU, same problem. Goes good under throttle, just idle is bad. I get weird looks at the gas station. People think it has a big cam.

Ford 7.3L Power Stroke (1999-2003) :: 2002 - High Idle While In Gear / Stay At 800 RPM
So finally got my truck running due to a fuel issue. Anyways been driving it for a week or two now, and I have a strange problem idk if it has been covered here or not.
Driving around tow etc if you come to a light or whatever and stop the rpms stay at 800rpm. Now if you shift it out of gear and back into drive the rpms settle back down around 650. Where is should be.
My guess is the torque converter is not disengaged all the way when it stuck at high rpm (800-900) for this situation. No cel, slippage, or crazy noises

Ford 7.3L Power Stroke (1999-2003) :: 2002 - High Idle In Cold Weather
Does the 2002 7.3 have an automatic high idle in cold weather?When you start it after it runs for a few moments it goes into high idle until you hit the accelerator. I had a 96 powerstroke before this one,it didn't do this. Just wondering?

2002 F350 single wheel 4x4, 280k miles chipped with a 6
My problem first started when the bottom of my sending unit broke off in tank causing me to run out of fuel at 1/4 tank. I dropped tank and repaired. A week later I noticed fuel dampness on my tank and discovered I crossthreaded cap on sending unit. About this time I started getting a shutter at slight acceleration only and a harder hit at idle. I thought air in lines so I dropped tank and reassembled. No air in line at all now but I still have a shutter so I replaced fuel filter in case of obstruction. No luck. Now since I have owned truck it has been a pain to crank in cold weather if it wasn't plugged in over night. It has been hard lately even in moderate weather since shutter started so I replaced both batteries today.
I replaced the ICP today also because I noticed the other day when there was oil on and around harness to it and when I unplugged it today the truck changed idle and there was oil inside. After I changed it I took it out and it still had the shutter and sound of a miss. At about 8 miles in it just died going down the road. I coasted to the side and it cranked right back up and drove home. The shutter doesn't fill as bad but there. Also I live in the mountains and on my way home after cutoff I had chip in Stock position and had to put peddle to the floor to climb hill. I've never had to do that. I'm getting worried I work for a living and caint keep throwing money at it aimlessly. I'm thinking at this point IPR or CPS. But I'm no mechanic so I could be completely wrong.
Ford 7.3L Power Stroke (1999-2003) :: 2002 F250 Starts And Runs With Rough Idle For About 10 Seconds When Cold
I have an issue with my 7.3.... the truck will not start if it sits overnight without being plugged in, even in 65 degree weather. It starts and runs with a rough idle for about 10 seconds after its been plugged in for an hour, after the rough idle is gone it runs great .. it will Stat back up as long as the truck is warm (70+).... I've replaced the batteries, glow plugs, starter (it was going bad) and fuel filter. .. also replaced the gpr today. ....

I purchased a 2000 excursion with the 7.3 a couple of weeks ago. The guy said originally in the add that it need #2 and #8 injectors replaced. When I went and looked at it he had already replaced them and said the it still has no power and needed the remaining 6 replaced. I purchased it as it was a good deal thinking I should be able to get it fixed for worst case a set of injectors. BTW the engine has little to no blowby and starts easy and idles great.
The problem it it will not build any boost (has external boost gauge). Actually the gauge only shows vacuum. With the truck in park or neutral you can slowly rev the motor to 2500rpm and all seems fine but as soon as you break past 2500rpm it sound like it is missing and starts blowing white smoke. The smoke smells like when a diesel heater runs out of diesel. If you try and drive it it has NO power and will not move out of its own way and will eventually start like it is missing and blowing white smoke.
The previous owner replaced the following:
#2 injector
#8 injector
UVC gaskets
MAP Sensor
Wastegate solenoid sensor
The first thing I did was start looking at the no boost issue and pulled the turbo. I deleted the EBPV while i was there. Also the turbine wheel was in very bad shape so i replaced the turbine wheel, shaft, seals, bushings and installed a new compressor wheel 5+5 wheel off ebay. Reinstalled turbo and the symptoms are the same. I also replaced the clamps on the spider with Tbolt clamps instead of the worm gear styles and it psi tested all piping and intercooler to 30psi with no leaks. Also the up pipes have already been replaced with the bellowed style so there are no leaks and it has a 4" straight exhaust.
I have since ordered oring kits for the injectors and also ordered the fittings for the fuel bowl so i can check fuel pressure. it has a new air filter, oil filter, oil and fuel filter installed.
The ICP sensor has oil in the plug but if i unplug it the symptoms are still there.
I have also used a scanner and the ICP pressure is approx 500psi at idle and the duty cycle is about 11% at idle. Also the HPOP looks to be new as it is very clean compared to the surrounding parts and i have checked the HPOP reservoir and it is full to withing 1/2" from the threads.

I am assuming that the injectors are original other than #2 and #8.
Ford F-150 - 1997-2003 :: 2002 - Howl / Growl Noise From The Front?
2002 Screw 4X4 with 5.4 ... Truck has 180K miles.
Howl / Growl noise we think from the front. Both front wheel bearings have been changed without improvement. A rotational issue as it only does it when moving and still does it if you put it in neutral and let it coast.
2 WD or 4 WD does not seem to make much difference. Been checking and testing everything without success. Drive shafts and u-joints are tight etc.
How to test it? It was my truck and is my son's truck now. They have run it on a hoist and tried to determine where the sound comes from. Going to try that again but it might be different when the wheels are not on the ground and there is no weight on things.
Ford 7.3L Power Stroke (1999-2003) :: 2001- Rough Idle - Power Loss?
Dad has a 01 one ton with the 7.3 and isn't real tech savvy so I'm posting for him. He is the original owner and has been complaining recently about the lack of power. Particularly the upper end. He is having to downshift way more often and where he used to not have to. And we've both noticed a very noticeable shake at idle. Not a vibration but a true shake. He changes the oil every 5000 on the dot and I've gone and changed the air and fuel filter and ran hose and see foam and royal purple injector cleaner through it with no results. Truck is all stock with 225000 on it.

I have 01 F550 6spd 4x4. sounds rhythmic, smooth at idle but just over 1200 is a pattern surge but doesn't sound like one cylinder, cel is off, ICP and pigtail changed as it was leaking , no change. From what I've read duty on ICP and IPR should be about same % I've included the codes I've gotten, I have the epc disconnected right now as I thought it was a wastegate issue, checking the ICP plug next,anything I've missed? It had a cyl 8 contribution at idle which I hear is common? Will changing CPS work with that one? Think it's a grey one. There's no water in bowl I replaced filter, since replaced ICP, pigtail, and bleeding fuel bowl and new filter the codes are gone but still misses, will be checking uvch, injector buzz test showed no faults. Old diesel guy said to flood with Stanadyne fuel treat?

Started my truck yesterday and drove about 1/4 of mile and all of a sudden I lost all power but was lucky enough to creep back home. Had a friend put it on a scanner and it spit out P1280 and P1316 codes. My truck will start and idle rough but has no throttle response and no power. I changed out the CPS and ICP and the problem still exists. I got an infrared thermometer and checked the heat coming off each manifold and the driver side was reading about 200 while the passenger side was reading about 75 while at idle. Pulled valve pan cover off the passenger side to check and see if the harness came loose and everything looked fine. So my question is do you think this could lead to a bad IDM?

I have a 2002 7.3L Screw 4x4. Will a 03/04 6.0L instrument cluster work in this truck? The 2 clusters appear identical. I put the 6.0 cluster in and the trans temp, and coolant temp gauge will not work. All the gauges sweep when it is powered on, but the coolant and trans temp lay flat, and the check gauge light is on. All other gauges and functions work. When I put my other cluster in, all gauges work fine. Is there a difference in the VSM, PCM, or the SCP communication?

View 5 RepliesFord 7.3L Power Stroke (1999-2003) :: 2002 F250 - No Power To PCM Fuse
I just finished a cab swap and I'm having a little trouble. Here's a link to what I've done : [URL] ....
KOEO the WTS light, battery light, SES light all stay on and no power to fuel pump. No communication with PCM (using AE). All fuses are good, but no power to PCM fuse (#22). When I apply 12v to #22, the truck will start and idle - but poorly because I still don't think fuel pump comes on. The idiot lights all stay the same.
I did get to pull codes while it was running and got stuff like IAT circuit high (its not plugged in), fuel pump relay short to batttery, and a few other short to battery things (park assist stuff IIRC). I thought that might have something to do with the redneck idea to boost the fuse with an external power source?
Just thinking while typing, I don't have 3rd brake light hooked up yet (just thought of that, I'll hook it up first) and bed/bumper are not installed, so no tail lights or park assist stuff is hooked up. I'm also not using overhead computer, so it's not plugged in.
My next step is to go back through all of the connectors and make sure something isn't 1/2 way plugged in or possibly plugged into the wrong place(s).
Looking thru the wiring diagrams is not a strong subject for me, but I was trying to figure out how power gets to the fuse and how PCM relay works (does it complete circuit to ground to energize the coil?).
Ford 7.3L Power Stroke (1999-2003) :: 2002 F350 - Lack Of Power
My issue I'm having - 2002 F350 7.3L has an 8 inch bds lift with 37/13.50 tires. I realize these tires are big but... while driving 100kms/hr or 60 miles per hour and I hit the gas the truck barely wants to move (without pulling a load). Thought maybe a turbo but I have no mechanical skills so here I am!
2nd issue, there's a bullydog chip in that truck when I bought it. he said he always ran it on extreme. I found it puffs way to much black when on extreme and on performance it seems a lot better so that's where I have it?.
3rd issue, the transmission gauge on the dash goes into red when climbing up hills ( I live in the rocky mountains so a lot!) but the bullydog chip says the tranny is only at its hottest 140C? I don't believe that's to hot but I do believe my truck is derating a little while the tranny gauge on the dash is in the red? is there any quick fixes out there for these issues.
