Ford 7.3L Power Stroke (1999-2003) :: 2000 - Codes P0603 / P0671 And P1670?
On the way home from work today as I pulled in there was a pulsating under when I pressed the brake pedal and the ABS light appeared on the dash. It didn't pull to the right but it felt kinda odd. When I start the truck, the ABS light comes on with the other indicators, goes off and then comes back on a split second later.
Haven't had any issues lately, and haven't had it worked on lately so not real sure where to start. I checked the VSS sensor on the pumpkin and it was relatively new, which means the prior owner had replaced it. Master cyclinder is full of fluid. I pulled the codes and it returned P0603 P0671 P1670.
Just sprang up out of nowhere. The speedo was not acting squirrely, just the brake pedal pulsating intermittently. Is there a VSS computer I need to replace?

Finally had a good scan done on my truck at the mechanics. The reoccurring codes were P0478 and P0470. It looks like a bad exhaust pressure control sensor. Looks like an easy fix.

Truck has a rough idle and finally just stalls out. I replace the under valve cover wiring harness and put in new glow plugs. With valve covers still off I started the truck in the issue still persist. I went ahead and unplugged each injector and each time the motor had a hick up .
What am I pulling apart and replacing next?
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 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.

I have a 2000 F350 4x4 CC 7.3L 323,000 miles auto trans. I have removed my tuner just to make sure that it was not the issue. The truck will run fine then all of a sudden the idle will rise then fall or shudder or go up and down and sometimes it will just Die but it always restarts. No trouble lights at all. I am not sure what is causing the issue?

A couple weeks ago my 01 7.3 with 265,xxx started ideling rough and stalling. I had driven in all day Sunday and the next day it started out of the blue! It would barely start idle rough and stall out no CEL. I have singed changed the icp, fuel filter and I have checked oil level. Also used fuel cleaner. Still had no luck. When I changed the icp sensor the check engine light came on and was no change I then got a ford oem camshaft sensor and my truck fired right up but still sounded like it had a little miss here and there drove it for a few weeks fine now back to the same thing it will start up and idle fine for 10 seconds then start the rough idle but won't stall out anymore just idle rough. I am stumped I can't get any codes to pull up and if oriellys uses there scan tool while the truck was running it would shut the truck off! I can't find any answers.

I just recently bought a 199 E350 4x4. I changed the injectors and it drove a little bit better but was still lacking power and was throwing a p0472(exhaust back pressure code) and a p0113(IAT sensor circuit hight output) code. Last night i put a new ebp sensor and the truck came back to life for about a half mile or so then went right back to the way it was. I took the sensor back off and cleaned it in case it some how got clogged from my short ride. It surprisingly did have some soot in it which i cleaned out. Also blew air into the ebps line while still mounted. Put everything back and still nothing. What could it be? Could i possibly got a bad ebps?
View 14 RepliesFord 7.3L Power Stroke (1999-2003) :: Rough Idle - Intermittent P1118 Code
For the last couple months I've been messing with a P1118 code. Started a few months ago when I noticed my fuel mileage was down 1-2MPG. Also sometimes a rough seeming idle (hard to tell with the diesel). Then it threw a P1118, so I replaced the temp sensor under the turbo. The code went away for a while then came back, fuel mileage didn't change. So I replaced the temp sensor in the air filter box.
The code went away AND my fuel mileage seems to have come back to normal. Now, code thrown again. Search on P1118 hasn't been super useful. Seems like replacing the sensor under the turbo is the trick. Also seems to come up in combination with a bunch of other codes with battery problems. I suppose it's possible I have some sort of electrical gremlin. It throws the code on startup and stays on until I shut it off. Doesn't come on every time, is off more often than on.
Ford 7.3L Power Stroke (1999-2003) :: White Smoke / Rough Idle And Missing
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) :: F250 Hard To Start / Rough Idle?
My 2003 7.3 f250 has trouble starting whenever the temperature is less than 65 degrees. If it is less than 50 degrees I have to plug it in for it to start. Once it starts it runs rough. I let it warm up and it still runs rough. Once I start down the road I'll get on it a bit and it takes off like something lets loose. It then runs geat for the rest of the day but does seem to still crank a little more than it should when I restart it through out the day.
The pickup has 152000k
List of repairs I have done to the truck:
-new gpr
-new glow plugs
-new uvch both sides
-new valve cover gaskets
-new blue cps
-new fuel filter
-new batteries everstart maxx 65n
The truck has an afe air intake, straight exhaust, and a super chips tuner set on mileage saving. It blows white smoke when first started but clears up pretty quick.

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) :: F350 - Surging And Rough Idle While Driving
I have an early 99 F-350 with 268K miles. It is bone stock right down to the factory exhaust. A couple months ago I started have a rough idle and surging while driving problem. I never got a check engine light but I borrowed a scan tool from a friend and pulled the following codes: P1690 (wastegate solenoid), P0381 (glow plug circuit malfunction), P0269 Cylinder 3 Contribution/Balance Fault, and P0284 Cylinder 8 Contribution/Balance Fault.
I did some research and everything I read said it was most likely the CPS. So I changed the CPS. The truck ran fine for for a few days but then it started acting up again occasionally. I noticed that most of the time when it acted up was at start up when the engine was cold and I also figured out that if I shut the truck off and re-started it (sometimes I had to do it 2 or 3 times) it would clear up and run normal.
A buddy of mine that has a 2000 F-250 said he had a similar problem with his truck and it ended up being the ICP sensor. We switched his ICP with mine and I changed my oil at the same time (because it was due for an oil change). My truck ran flawless for over 2-weeks (over 200 miles) so I put a new ICP in my truck. Note: my buddy did not experience any problems with his truck with my ICP in it.
I've put about 700 miles on the new IPR and the truck has started to act up again. Once again shutting the truck off & re-starting it will clear it up and still no check engine light. I took it to a local "diesel specialty shop" while it was running rough and they hooked it to their scanner and got P1280 (Inj. Control Pressure Low), P1690 (Wastegate Solenoid Fault), P0381 (Glow Plug Indicator), P0269 Cylinder 3 Contribution / Balance Fault, and P0284 Cylinder 8 Contribution / Balance Fault.
They never did anything other than hook it to a machine & check the codes but their diagnosis is my High Pressure Oil Pump is going bad and my #3 and #8 injectors are going bad. They recommended I let them replace all 8 injectors and the High Pressure Oil Pump. The problem I have is they can't give me a REASONABLE explanation as to why re-starting the truck a few times clears up the problem.
Ford F-150 - 1997-2003 :: V6 Rough Idle / Black Smoke / Throwing 6 Codes
so i bought this truck about 3 months ago and it was running real bad when i got it, I went ahead and changed the lower and upper intake gaskets, cleaned throttle body, egr ports on lower and upper intake, did timing chain cover gaskets and 3 bad injectors i found while doing gaskets, truck ran better but still black smoking(running rich) and getting 8 mpg. So I changed fan clutch,fuel pump fuel filter,airfilter,MAF sensor(old one was pulling 14.4 volt), DPFE sensor and all 4 oxygen sensors(old ones carboned up and real sooty).
I've checked my egr valve while idling and when it opens the engine just about stalls, truck seems to be running better but CEL light came on again and is throwing these CODES:
P0453 (evap emission ctrl sys pressure sensor high input),
P0141,
P0153,
P0135(oxy sensors),
P0401exhaust gas recirculation flow insuff detected,
P0460fuel tank level indicator circuit error.
And I believe I've told everything i know ...
