I have a 1999 F-250 PSD. Once or twice a week on start up, the engine just chugs. Certainly not hitting on all eight cylinders. Idiles real rough. After letting it warm up for a few minutes, hoping it will clear up, I drive for a few miles and shut down the engine. After a few minutes I can restart up and engine runs as smooth as new. Has me totaly confused. The Ford dealership is of no help. By the time I can get to dealership its running OK. Since its not doing anything at that time they do nothing. I have left the truck with them for a week at a time. And of course they can't get the truck to any thing wrong. Once they switched me to Ford brand motor oil, thought I might be using the wrong oil. I use Rotella T 15W40. Not sure what that was suppose to do. But noticed no difference. Have swithed back to Rotella T. Has anyone expereniced this problem? Were you able to correct this?

Bill,
With todays vehicles your complaint could be caused by many many differant things from wires to componant/mechanical failure. It's just about impossible to diagnose an intermittent problem such as this one, especially on a forum. There are as many potential answers as there are people who post on this forum, thus you will get several opinions. So my guess would be INJECTOR(s).
Carbon can build up around the injector that distorts the spray pattern. This can create your intermittent complaint. Try purchasing a tank additive. Run a tank of gas with additive and see if that takes care of the problem. This will be your least expensive way to go rather than paying diagnostic time to have someone basically guess and throw parts at it at your expense.
There are many people out there who can feel your pain cause they have lived through troubling hard to pin point car problems too, they drive you crazy.
Good luck,

Bill,
I have a 1999 F250 PSD and have had similar problems. Mine smoked like crazy when it was cold and at times it would barely run. The dealer changed the glow plug relay but that really didn't change anything. I also have had problems with water in the fuel while pulling the 5th wheel on the road. On the last trip to Florida (from Wisconsin), I had to drain about 1/3 cup of fuel from the fuel filter 4 times ( I carry some Tygon tubing to hook onto the drain line and a milk jug . As soon as I drain off just a little bit, it runs just fine. In discussing this issue again with the dealer last week and talking to others experienced with this engine, it has been strongly recommended that I add an additive to every tank of fuel such as Howes Lubricator Fuel Treat from Flying Js or Power Serve has a product too I understand. They are telling me that this engine needs "good fuel" which means that the only way to do that is by adding a C Tane (spelling?) booster, something for water and an injector cleaner - which the Howes product is (all in one).
I will be very interested in other comments that you get on this subject. I am also anxious to try adding the Howes product to see if it helps my truck. Don't get me wrong, I love the Powerstroke engine but it does have this peculiarity apparently. I also want to check Ford-diesel.com for answers. You might also consider checking that site.

Bill,
You might try posting your concern on the WWW.Ford-Diesel.com site, there's a bunch of folks on there that know all about these diesels.

Cetane is the measure of ignition quality of diesel fuel just as octane is the measure of ignition quality of gasoline.
A higher cetane number indicates faster burning. (High octane gasoline burns more slowly than low octane which makes high octane suitable for high compression without preignition.)
With good quality, clean, dry fuel, you don't need an additive. If you have a problem, then a suitable additive for that particular problem might help. It's always a good idea to carry a bottle or two of multi-purpose additive with you in case you get a tank of low quality fuel. As always, buy fuel at a station with high volume if you can.

Hi Bill.As Russel said its hard to diagnose,and solve this concern here,but it sounds like your getting air in your engine oil system.Your DI injectors are operated off from engine oil,thats why your dealer tried changing oil,as quality and quantity are very important to this system.What may be happening is your oil pump has started to scuff,(get grooves worn in it)and looses its prime while setting overnight.The engine has a oil reservoir with a stand pipe in it so it can't back feed,it starts up and runs off the reservoir until the engine oil prime picks up but now has air in it and misses for awhile until it purges.After that it runs good all day.Just a suggestion,but i have seen this before,and could progress to a no start. GoodLuck! F-150,Jayco Fiver
