I am on my first diesel truck a 2004 F350 Super Duty. It is a 6.0l Diesel with 120K miles. My issue started last week with the WIF and Glow Plug coming on for about 2-5 seconds. When that happened the truck dropped to an Idle. Once the lights went out, the power was restored. This happened 1...

I have a 99 7.3, it is stock No chips/Mods. Starts/drives OK when cold, will drive for 10-15 minutes perfectly fine then pow. Fuel filter was replaced recently. Oil is not excessively out of mileage. It started One day on my way home from work I stopped at the grocery store (and everything was...

Hello! My truck is throwing a bunch of codes, P0069, P0299, P0404, P0405, and P0470. It has also thrown a P0341 but has since gone away. This all started when the temps here in ND dropped below zero. I haven't had any issues from the truck until yesterday when it was really cold (-16 f) and I'm...

This is a 2006 F350 Crew Cab Automatic. 125k miles. Pretty much stock minus straight pipe off turbo. Several months ago, had no hot start issue develop. Took to shop and they replaced IPR and did turbo seals and most of top side o-rings, dummy plugs, new oil cooler screen (it was blitzed)...

I was driving, and was at a stop light. My idle was fluctuating 200-300 rpm. I did notice earlier when I was cleaning my intercooler boots that the plastic part on top of the IPR moves around. Also, whatever it is, is very sensitive because it will be rough, the stop at ramdom times. I am at my...

Hello guys, I have a 2002 Ford F250 7.3L that I bought new in '02. Recently the engine lost power and ran really rough. I brought it to my local mechanic who had to replace the main wiring harness and the passenger side Under Valve Cover Harness. They also replaced two injectors on the...

Greetings- i am new to the site, and love all the info yall put on here. I have an 04 250. K&n intake, 4" exhaust, and hypertech max energy tuner. Today while stuck in wonderful Dallas traffic, she started idling rough. No cel, just sounded like it was "missing". I was able to limp her home, and...

Well shoot, I have had the worst luck with this truck. 2004(late model) crew cab short bed. Egr delete, airaid intake, studs. I have done studs(twice) on this thing in a matter of 15,000 miles without running a tuner. Heads were pressure checked and milled within ford tolerances the second time...

I have a 99 f 550 7.3 with 200,000. Just recently the fuel system was contaminated with engine oil. I replaced all 8 injector seals and cup sleeves. Replaced the rail fuel pump and fuel filter. The contamination is fixed, but after a couple of the days of using the truck it made a hissing noise...

Hello I'm new to the forum, I just bought a 2005 6.0 Monday and I've been having a problem with rough idle, and slight missfire around 1500RRPMs in most any gear (happens once in awhile) and off and on power. The truck has been sitting for about 6-8 months. First thing i did was change the oil...

Hey all, I have had my '97 XLT, quad cab, DRW, automatic for just over 2 years. It has 221000 mi on it. Recently I noticed that when I shifted into D, or started from a dead stop after having driven for a while, first gear felt like driving a manual and very slowly letting out the clutch. I...

When I try to start my 2000 Excursion it sounds like the batteries are low. It turns over a little slow and hesitates and then starts and runs fine. The batteries are good and so is the starter and alternator. The air filter is a little dirty and will be changed tomorrow. Any ideas of what...

I was driving down the express way the other day when all of a sudden out of nowherethe engine started losing power. It was not a quick loss of power but is very slow over 20 seconds loss of power until the engine eventually stalled. it would not restart. I had to have it towed back to my house...

So I bought my truck in August and it ran okay for $2200. It is a 95 7.3. I now about $6000 into the truck after messing with it since thanksgiving and it still is not running right. I have replaced all of the injectors. IPR. and many other things. I believe the only problem left is that it...

My HPOP was at 3800 psi. Had a really rough idle and lots of white smoke. Took pump apart and there was a check ball out of place. Put it back and replaced IPR and now its back down at 800 at an idle. Problem is the truck is still running insanely rough and blowing white smoke. Had injectors...

The truck is running really rough with lots of white smoke. The only thing I had done to truck was PCM tuning by DP but I do not believe the PCM is the problem because it ran a friends truck just fine. I took it to local shop and they checked PCM, IDM, IPR, ICP, CPS. The scanner showed the HPOP...

Ok, I am lost on this one. here is the description of what keeps occurring. The truck starts just fine and runs flawlessly, just like always. Then, out of nowhere the service engine light pops on and I have a terribly loud and rough idle and no power to speak of. Pull over, turn the truck off...
