Ford 7.3L Power Stroke (1999-2003) :: Six CEL Codes / Stall Out At Times / Shutters Or Pops Between 1800 - 2500 RPMs
I have a 1999 Ford F-350. I have six codes from my truck. The codes are P0237 P1119 P1690 P0500 P0603 P0344. My truck runs, but likes to stall out on me for no reasons at times. The other problem I am having is between 1,800-2,500 rpms, she shutters or pops.

My excursion's trans is slipping on the 25hp tune up high in the RPM band and shutters when up shifting. I have dropped to stock most of the time, but I know i am on borrowed time.
I had a JW trans in my e99, and there is no question on the durability and performance of the transmission. The price has gone up a lot, but that's maybe not the big issue.
I live in the mountains and spend a lot of time pulling and just driving in that 40 to 60 mph range over mountain passes. That is basically where I spend ALL of my time.
The distance between 3rd and 4th is driving me CRAZY! I have researched everything from swapping to a manual, to PCS controllers, to trying 4.11 gears, to overdrive units.
Swapping Manual: ZF6 is the obvious candidate, but I have read the swap is not probably something I have the skills or tools to do. I have also read that the performance of the ZF6 is sub par. But it seems like it would give me my 3.5 gear that I am looking for.
PCS Controller: Looks cool for a way to have control besides using the tree shift. Maybe a compromise on not swapping in a manual.
4.11 Gears: I get pretty excited thinking about the low end torque etc. I go off road almost every week, and like I said, I hardly go over 75 mph. But once in a while I do. Right now, the truck turns about 2300- 2500 rpm at interstate cruising speed. Looking for 4.10s rpm in that range to compare? Also, how bad of a fuel economy hit would I take? What is the cruising rpm of 4.10's between 60 and 65 mph, or in general what is the rpm change?
Overdrive Unit: I have always been interested in more gears, but I read about someone who installed one behind a 7.3 and didn't have they great of results. To the point where he said it wasn't worth it.
Ford 7.3L Power Stroke (1999-2003) :: 2000 - Smoke On Cold Start - Oil Filter?
2000 F350 with 340000 on it, have had it for the last 140000. It's an old service truck from south west gas with one owner in between them and me and he put about 5000 on it. I have the big cylinder open air filter, billet compressor wheel, 4" exhaust all the way and an Edge tuner. Don't have any codes I can pull with the tuner. Have been good to me so fare only need regular maintenance, but always had smoke out oil filler with a little pulse.
2500 ago I changed oil and add 1/4 of Lucas oil. 3 days ago when I started in the morning it smoked white smoke out the exhaust as a steam train and idle rough, but cleared up as I went down the street and will do so every time I start cold or warm. Ok, might need new GP, did that yesterday yet the same. Now I start checking stuff and have smoke out the oil filler as a steam train so the cap won't stay.
I know it sound like alot of problems, just try to verify some of them. The smoke out oil filler is blow by? The smoke on start up is that related to bad injectors? Can a bad injector dumping fuel create the blow by? Coolant level ok Transmission fluid level ok Engine oil Rotella T6 added 3 quarter in 2500 miles. I do not have a scanner or any other advance test tools.
Ford 7.3L Power Stroke (1999-2003) :: 2000 - Hard To Start On Cold - Oil Leaking?
20 degrees out this morning truck not plugged in, didn't want to start had to cycle 4-5 times, each time waiting for glow plug Light to go out.
Finally cranked didn't sound pretty but cranked. Once it started idling on its own got out and seen a puddle of oil under the front of the engine drivers side center kind of.
Got up on the truck and shined a light in the valley and seen a puddle in intake valley. Heres my question? Where did this oil come from? Once it warmed up it quit and oil kinda disappeared from valley???
I had turbo off a few months ago because I thought I had a bearing down in it, but found some bolts lose. When I put turbo back on I broke the wire plug on front of the pedestal so I just left it unplugged. Very hard to cold start now that that is unhooked.
Did leaving this unhooked create a hard cold start? Should I put another pedestal on it with the plug or install one without it? Also will it hurt to leave plugged in overnight?
Ford 7.3L Power Stroke (1999-2003) :: 2000 - Lopes At Start Up When Started Cold
I recently purchased a 2000 7.3, when it's started cold it's lopes at start up unless I give it some gas and then it's perfectly fine. If the truck is plugged into the engine block heater it starts normal. I changed the oil the day after I bought it and put 15w-40 in it and then the rough idle started. So I don't know if it was like this before or because of the thicker oil I put into in the cold. It also has a service engine soon light on and the code that comes up when read is to the icp sensor. When looking st the sensor the blue wire going to it looks cut and is disconnected. How would I reconnect these wires and see if that makes the check engine light go off.

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've got a 2000 f150 with a 5.4 and 135,000 miles. The other day it was driving fine then i stopped and got gas and after that it was boggy and running rough so i thought bad gas but i ran through that gas and got more at a different store. The cel came on i got it checked it was misfire cylinder 1 so i put new cop, spark plug, and injector. Unhooked the battery and then the light came back on so i ran the code and now im getting a p0171. I checked the pcv and sprayed around the intake and vacuum lines. I also checked the pcv hose and elbow in the back and i found nothing its a fairly new hose. So, it does run rough it shutters a lot.
View 2 RepliesFord 7.3L Power Stroke (1999-2003) :: AC Stopped Blowing Cold
My 02 F350 7.3 new to me trucks ac stopped blowing cold. Not air gap issue (shims have been removed prior to my ownership-I pulled hub and checked), the charge is good (according to the shop I went to for evac and refill), and the compressor's cycling quickly. I'm no HVAC guy by any stretch. I have a cheapie gauge from days long ago that I connected to my low side port (which I know isn't definitive) and it reads from 25 to about 40/45 depending on the cycle.
Additional info that may not be anything:
1) Where the line goes from accumulator to evaporator the foam seal is slightly messed up and I feel ice cold air coming out of the housing.
2) The line is warm before the orifice and cold after it.
3) The lines going to the accumulator are both hot (after taking it to shop, before were lukewarm).
4) The condenser doesn't seem to have excessive plugging and I have rinsed it with garden hose sprayer with no difference.
5) The air from the vents blows good, just warm.
6) I've replaced the actuator for the blend door already.
Ford 7.3L Power Stroke (1999-2003) :: Cold Crank No Start
I have an 02 f250 230,000, first 7.3. I've owned it since Oct and put less than 6,000 miles on it. I have another cold crank no start. New glow plugs and Glow plug relay last weekend. Worked fine that weekend. It sat all week, then crank no start fri night, it was like 70 degrees for the high that day. Plugged it in over night and it started. Did not fire right up cranked it for a couple seconds. I drove it all day, started every time. Valve covers have 5,000 miles on them. Fuel Filter heater fuse not blown. But don't know how to check it for sure. And don't know where to go with it from here. Getting frustrated with crank no starts. No troubles found.

Ford 7.3L Power Stroke (1999-2003) :: F350 - A/C Is Not Blowing Cold As It Should
99 f-350 crew cab. The A/C is not blowing cold as it should. Have already replaced the compressor and clutch, orifice tube and accumulator, also cleaned evaporator coil and put a new blower motor on, also a new blend door actuator. Also put a valve in to block coolant from the heater core. System has had vacuum pulled and charged correctly by my mechanic, he says he doesn't know of anything else to do, that it was as good as its going to get. Ive been in 2 more trucks identical to mine and the A/C will freeze you out, as to where mine will not come close. Temp coming out of the vents barely gets down to 60 degrees
View 14 RepliesFord 7.3L Power Stroke (1999-2003) :: Rough Start At Cold?
I just started having a cold start problem with my '02 Excursion this fall and I'm at my wit's end trying to fix it. Truck starts fine above about 45 degrees and when it's warm. If I plug in the block heater it also starts fine in the cold. If it's not too cold I can eventually get it started by continuing to crank it. It blows white smoke while cranking and for a few seconds after it finally turns over. Smells like fuel. Runs rough for 30 sec after starting when it finally turns over. Definitely seems like glow plugs aren't working. This truck started no problem on GPs alone without plugging in down to -20 deg F before this year.
I started by cleaning all battery connections, including the two ground posts on the engine block, I replaced one bad battery (diagnosed by Autozone; other one was OK), I checked the resistance of the glow plugs (only a few years old with about 30k miles on them) through the connectors on the GP control module (all were about 1 ohm), and confirmed 12V at the power pins in the GP control module connectors. I then replaced the GP control module and the problem is still present. Battery voltage drops from about 12.6 V before I start the GP cycle to about 12V when I turn the key to "ON" and the GP light comes on. How much should the voltage drop when the GPs are on? What the heck else could be wrong??
Ford 7.3L Power Stroke (1999-2003) :: 1995 - Oil Leak When Cold
I have a 95 powerstroke as a daily so I realize the common oil leak issues and where to start. Today at work I came in to our 2002 7.3 with a puddle of oil underneath of it. It's a service truck I'm the mechanic and I honestly after filling it could not get it to leak I tried everything. A guy had come in and started it after sitting for the holiday and it sat and idled and leaked probably 2-3 quarts. They shut it down and I came in I added probably 1 1/2 gallons to get it full again. Has almost 300k after I had gotten there they had already warmed the truck up and it had cooled back down. It's coming from the driver side (axle frame rail and leaf spring) are all covered in oil but no obvious signs when shut off idling under load anything of an oil leak. I tried everything to get it to leak and not a drop.

Ok truck would not start when cold outside. So I put a gpr on truck. Truck alt would only put out 11.5 ... After I put it on. So I put 4 new alts on all read the same 11.5 and the battery's would drain over night. Turns out they gave me a starter relay. So I have the proper one now. Now when u turn the key the everything is flashing the dash dome light buzzer. But take one of the small wired off the gpr, it stops but I have no power to the starter. It's been 2 months of hell trying to figure it out.

So back ground is as such. Truck started fine before I replaced the hpop with t500 and did the driven diesel regulated return. I have double checked everything is plugged in. Now when I try to start it cold it will just crank. Yes I get smoke and oil pressure both places. If I give it a shot of ether it will start right up and run fine all day. What am I missing? Yes I know ether bad.

00' 7.3 is acting a little strange lately. i was towing a 15 foot trailer the other day for about 250 miles that wasn't all that heavy and my foot felt like it was very close to the floor. I had it to the floor and the truck would only go 60. now even without that trailer its better but still i feel as if i have to really put my foot down into it to speed up. if i go all the way to the floor in o/d it'll downshift and start speeding up but very very slowly then i run out of pedal and am at the floor, a lot slower than before. Before i wouldn't get to the floor and id already be moving pretty good. but now i gotta keep it pretty much 3/4 way down and keep it there to get up to speed and stay there. truck has 253k no tuner or programmer just 6637 intake and an exhaust, ww2. leveled on 35's. the tranny isn't slipping or at least doesn't seem to be. She doesn't shift perfect but its not anything crazy bad for stock with 253k on it. maybe something wrong with the actual pedal? or hopefully not but maybe the trans or motor , or maybe a sensor or something?
