Idle's Rough, Runs rough, No power
I have a 99 7.3, it is in a f450. I just spent $ 4300.00 dollars on this truck. Oil pan was leaking and had a noise (bad bearing in transmission) manual 6 speed. So I took it in to have these problems repaired and also a complete service including brake system. Thought I was getting it in shape for winter or was considering trading for new in a few months. After the repair bill I had to keep it.
Just after I got the truck back (1st or 2nd day) the motor seemed to quit after leaving the highway. I had droiven 200 miles, It may not have quit, maybe just lost all power as all the gages read fine. I could not pull over where I was so I left the clutch ingaged hoping it would restart, it regained power in about 20 seconds. It worked fine for three or 4 days then while on the highway passing traffic it did the same thing. Only it took about a minute or more before regaining power.
I thought it was bad fuel so I changed the fule and air filter. Even though it was suppose to be a complete service it did not look like the air filter was changed. I also added some diesel conditioner and topped off the tank. It was fine for a week or so then on ocasion it would lose power for 1, 2 or 3 minutes. Also each time the check engine light would come on.
Friday when leaving a job it started and ran fine for about 1 mile then lost all power and ran rough. This was the worst power loss I think yet. I stopped let it idle for 3 or so minutes, it idled very rough. Shut it of and let it sit then started it again (started hard) still missing. Reved it to 2000 it seemed eventually to get a little better. I then proceeded (very hard to get going from stop) and drove along the highway at 20 miles an hour. all gages read fine, check engine lite was on. After about 20 min it took hold worked well and engine lite went off. Worked well all the way home, next morning it started hard and run very rough, had no power. And so it sits in my yard.
Changed the cam sensor as I had the quiting problem before and relly hoped this was it even though it did not quit.
I stpped to get the code Friday on the way home, truck was working well at the time, and no code was picked up.
I know it should have stored a code but this is the same place I have gone in the past for codes and they picked them up fine. Truck has 250000 on it.
I am very sorry for the long post, just hoping if I give good information someone can help. Really need the truck.
