Ford 6.0L Power Stroke Diesel :: Truck Pulls Really Hard To The Right If Going Over 40 MPH
Apr 17, 2016
If I am going over 40 mph and I have to brake hard my truck pulls really hard to the right. I mean so hard it will take me off the road. My truck is a 2004 f250 with 147,000 miles.
In the last six months I have replaced both hubs, rotors and brakes. I really drive like an old man so I don't know how long I have had this issue. Just someone pulled in front of me on the freeway and I had to brake hard and I found this out.
I have checked both front capilers and brake lines and those are fine. I have brand new tires on it. I really have no clue what is going on. I have pulled the brakes off three times and checked everything out and it looks good. If slowly push the brakes everything is great, it is only when I have to really slam on them.

So I've been noticing the truck pulls left when under braking. So, I replaced the front calipers. Now, it still pulls left. When I got home I felt the discs on all corners and found three about the same, barely touchable, and the front left a little warmer. So, it seems its braking more, but its brand new. So, what should I do? They are also pulsing a little.

Truck pulls to the left while braking, pretty bad. So, pulled the front right wheel off thinking the pins are stuck again as last year. Bottom pin was fine, top pin pretty gummed up but not froze so I cleaned it up good, used thin layer of the good stuff, put back together and test drove........same thing. Pulls left upon braking just as bad as before. Caliper pistons seemed fine, didn't take much to compress them either. Would a right rear cause this?

Long story short, 7 out of 10 times when I turn on my headlights (while driving) my ABS light will flash, all gauges will drop to zero then instantly resume their place, lights are on and everything seems to be normal..
Recently it seems that when ever what I just explained above happens, and I press the brake pedal shortly after the truck pulls to the right. Harder I press the brakes the harder it pulls the truck off the road. Pretty scary stuff..
Brakes look good. Although I haven't checked the fluid or for any real notable leaks.

I removed all 8 injectors because my truck felt like it had a dead cylinder one morning after I did oil change and filter and fuel filters. Truck ran great the day of the fluid change. The next morning however truck was hard to start no power at all nothing. Felt like a dead cylinder so removed all 8 injectors and ohm them all ohm at 0.4 to 0.5 except number 4 injector it ohm at 0.4 and 0.7 that's not in spec right or am I wrong? Do I need a new solenoid? Keep in mind tho number 5 and 8 injectors had contribution codes but they ohm good. So I'm going to tear the injectors apart and see what's what. But my question is do I need to replace number 4 injector solenoid?

On Saturday I drove my truck 450 miles, all of it towing, in hilly New England. The turbo boost gauge was operating at 20psi or higher for many of the hills, and the 13mpg average was indicative of how hard the truck was working (normally empty I will get 20+). The next day, I drove it about 3 miles and it started a regen. Why? Wouldn't it have been passively regenerating for most of those miles? A steady 75mph for hours at a time?

I have a 2006 that shuts off in a hard pull, if I wait 3 minutes it starts again. I hooked up my scan tool and when it dies and I crank it it only builds 200psi oil pressure, let it sit it builds enough pressure to run fine. If I dont push it over 3500psi for more than minute it wont die pull a hill it dies again. Is it the hpop or an o-ring.

Earlier this week the truck was hard starting every time. Tested the batteries: 12v engine off, 14v engine running, all good.
The next day it threw a P0284 – Cylinder #8 contribution/balance, and was clearly missing on a cylinder. Despite the lack of a puff of smoke at start-up, I was pretty sure it was an injector. So I ordered one from White Bear Lake, and a fuel pressure test adapter from Strictly Diesel. Then I decided to do some testing with AutoEnginuity. Tried the injector buzz test first and got a note that the truck was not capable of performing the test. Tried starting truck and gauges swept and wouldn’t turn over. Tested batteries again: main battery 11volts, aux 12volts.
I got the batteries in and the stupid thing runs like new. Only codes are P1000 and P0603. Truck passed the injector buzz test, and cylinder contribution test graph is almost a flat line.
Take-aways:
1. Bad batteries can cause all sorts of havoc.
2. Always use a voltmeter that displays tenths of a volt, because if it’s only showing whole volts, it could be rounding up. The 12 volts from my first test was probably more like 11.6 volts.
3. Always do as much testing as possible before buying parts.
4. Costco does not sell Kirkland batteries anymore. They only stock Interstate, and the Interstate warranty has dropped from 36 months free replacement to 30 months.
5. The Walmart and Autozone batteries with the five year free replacement are “out of stock” and I’m guessing they won’t be back with Interstate dropping their replacement dates.
6. Most of the car batteries in the US are made by Johnson Controls.
7. Motorcraft batteries did not get very good reviews.
8. Interstate said that AGM (absorbed glass mat) batteries stand-up better to the additional vibration and heat experienced under the hood of a diesel, but they are significantly more expensive, and not all the brands offer an AGM with a better warranty than their best lead-acid offering. Also, the guy at Sears said AGMs are only beneficial for newer cars that continue performing electronic functions after the ignition is turned off. He said he’s seen lead-acid batteries outlast AGMs, but didn’t specify if those were out of diesels or not.
Questions:
1. Can I expect the P0603 to go away after the drive cycle is complete?
2. What should I do with the new injector? If I return it there’s probably a restocking fee. If I wait for a complete injector failure I don’t get the core charge back until then. With the FICM compensation, I don’t know of any way to identify weak injectors without IDS.

Have 65k now..OEM breaks. Never an issue.. going along today had to make a fast turn left into a parking area. Hit the brakes doing about 50 made the turn. Slowly found and kept rolling to a parking spot. Went to apply the brakes and found the pedal was rock hard. The truck kept rolling slowly. Pure luck I was were I was.. I tried to shut the truck down and restart. Still rock hard pedal in up position. No breaks.. not enough to stop at idle. Checked the brake fluid and it was fine. Went inside the store to grab the delivery and when I came back out I tried to work the pedal down.. I felt some give.. put it in reverse to check it out..(couldn't go ahead no room.) slowly the breaks came back. Has been fine since.. driving all over town today. No codes or engine lights.

Had mechanic check suspension components, alignment is fine, nothing looks damage or needs to be replaced. Tires are 35 inch and practically brand-new...

So my 01 has been parked in the garage for about 2 months. Normally on battery tender but it accidentally got unplugged and I didn't realize til yesterday when I went to start it. So I got the battery charged up and put air in my rear drivers tire since every time it sits it goes flat. Well I did all this I so I could take it to get tires today.
Driving to work and its shaking pretty bad at highway speed. Don't recall it doing this yesterday. Never really did this before either. The truck also pulls hard to the right. Its done this for a while so I'm not sure if it's just the tires or needs alignment or something else. Or all of the above.
I'm mainly concerned with why it was shaking. The front tires don't look low however I will check the pressure on my lunch hour today.

What besides a 4" exhaust can I do to lower EGT? When I tow with my tow tune the EGT gets high on long steep pulls. Would like to be able to use it with the tune because there is more power and it pulls nicer, but I want to lower my EGT. I have a 4" flo pro system coming. What else can I do? Would a new intercooler make much of a difference? Already have an S&B cold intake and Banks Hi Ram.

Just replaced break pads and rotors. Inner pad on left side was gone leading me to believe slides were not working properly. Pulled apart, cleaned and greased everything, and replaced pads and rotors. Calipers seem to be working fine. Now when I break hard, the truck pulls badly to the left. When I break softly, it seeks normal. My front end is a bit out of whack and veers just a bit to the left. Do you think this is my issue with the breaking ? I'm getting new tires and an alignment soon but was just curious.

My 2003 F250 6.0 pulls to the right when driving at any speed. In order to keep it going straight the steering wheel must be slightly tilted to the left, not much but a little. When the brakes are applied hard it will go to the left slightly if you are not holding the wheel good. Neither of these are terrible, just a nuisance. I'm worried about uneven tire wear too. One front wheel bearing was replaced a few weeks ago. It had this problem before that and still does after. Does this sound like an alignment or maybe something more?

The first has I replaced my tranny with a stock 4r100 tranny and torque that only has 75k on it. The guy was doing a 6-speed swap. After I had the tranny and torque converter and a new tranny cooler installed, the tranny shifts real hard. I think it may be from my DP Tuner. Even on my economy tune driving it very easy sometimes, it jolts into gear pretty good.
I was wondering if I could just get a shift kit to maybe correct that and if so if I would have to drop the tranny to install the shift kit. I saw a bully dog kit for like 75 bucks, however, I don't really have the money to have the truck in a shop and I would really like to not drop the tranny and not lose all my tranny fluid if possible (very expensive).
Also my other issue, the truck in warm or cold weather is very hard to start. Half of the time it takes two tries to start it. It will crank and crank and no go. Then the second try it fires right up. It has two new batteries, where do I start? Is it possible that the starter is just getting old or is it fuel or oil pressure related possibly?

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.

First post since I bought my powerstroke. I was looking for some diagnostics.
On my way to work this morning and the truck started chugging like it was wanting to die and had no power, the pedal was to the floor and I was barely moving. I was able to nurse it to a parking space at work and pulled the codes, using the Torque pro. This was what I pulled:
P0284 - Cylinder #8 contribution/balance
P0299 - Underboost
P0611 - FICM
P0401 - EGR
P0671 - Cylinder 1 glow plug
On the way home I didn't even hit 5 miles and started into the same symptoms. So I decided to call for a tow, because my commute is about 60 miles one way. In waiting for the tow truck I disconnected the batteries and reconnected them thinking that it might "reset" something. I started it up and the same thing occurred, so I tried revving it up, and starting it up and shutting it down on and off for about an hour. Thinking I picked up some bad fuel. Drove it for a short distance and found things were getting better. I was able to make it home and pulled the codes again. It came up with these:
P0284
P0603 - Internal Control Mod.
P0611
P1000
Also on the ride home I had excessive amounts of black smoke from the exhaust and found a couple of large drops of oil on the driveway where i normally park, larger than what I normally see.
So my question would be what is the cause of all of this?
A little about the truck. it is a F250 CCSB with about 139xxx miles on the clock. I bought it from my brother when he had it he had the FICM replaced (with the 58V option) and the Bullet proof EGR installed. I replaced the fuel spring with the blue one shortly after I bought it.

I just got my new up pipes put on as well as a 38R and pulling a hill hard my truck will hit about 22 psi then drop off slowly I have an electronic boost fooler wich has been on the truck since new pretty much but I don't get a CEL at all is this what I should be getting and I was on the 80hp tune? I ordered new boots and plenum inserts they just haven't got here yet. I know I had a leak before on my old up pipes because they rattled every now and then and I could see exhaust coming out of them when it was cold out but I could hit about the same 22 boost with my old setup. So pretty much nothing changed boost wise except it gets up to boost faster now. I would say it's defueling but I was always told the CEL would come on if that was the case.
