I have a 2000 Ford F-250 with a 5.4 liter engine. It gets very poor gas mileage and bogs down when you try to accelerate. I have had it looked at by a mechanic and I asked if it could be related to the catalytic converter or the fuel injector. They gave me a bid to repair other problems with the truck but did not mention either of those things. I recently had the mass air flow sensor replaced. Has anyone else had this problem or have any suggestions for me?

I have a 93 F-250 with a 460 cube engine. It was running fine till the other day I was on a trip towing a trailer, itstarted sputtering and I could hardly go up a hill, maybe 10 mph. I stopped and the rig would idle but would not rev up, shook bad and I thought my tranny was going out but it idled good, just when I tryed to accelerate it would cut out. I replaced the gas filter, which had diry gas come out the back side, and replaced the oxy senser, neither helped. I got it onto a trailer and hauled it home, itstarted fine to get on the trailer and off, but in my shope itstarted and then died, will not start now. Any ideas, there is pressure in the fuel rail, have switched tanks back and forth , makes no difference.

2003, F350, 5.4ltr, auto., 140k miles. Fuel pump problem every 10k/15k miles. The fuel pump has been replaced 8 times, and ready for #9.
The symptoms before it goes out are: Lose of power under a load, erratic shifting under a load, erratic engine operation (RPMs go up to (4k+) but vehicle speed goes down). If you let up on the accelerator, engine RPMs come back to normal area and as long as you don't put it under a load it will keep running. If you try to accelerate rapidly, it will almost quit running and continue to slow down.
The strange part of this is that while this is happening I can put the truck in Neutral turn the key Off/ON and it will run normally for another 30 minutes or so. (I know this is an unsafe practice while moving but I'm getting very frustrated.)
The 1st pump went out at 15k. Ford dealer replaced the first 3 stating "contaminated fuel" was the cause. The next 5 were done by private shops. They could not give a cause other that a bad pump and did not find contaminated fuel. They could not explain the Neutral Off/On temporary fix either.
It has been suggested that a ground wire might be missing of loose, but I could not tell. At the next replacement I am going to have a ground wire installed from the tank to the frame. At this point it can't hurt.
If anyone has had a similar experience or has any suggestions, all will be considered.

It was the catalatyic (sp) converter, plugged so tight the exhaust couldn't go out.

I've a 2004 F150 bought new 50k miles same problem.Went back to dealer once they reprogrammed computer that was fine then the driveability problem came back.Dealer hasn't a clue.I tried the Hypertech programmer recently,truck kept stalling at stops so reprogrammed to stock.
The truck is an excellent highway cruiser but around town where we drive the most not so good.As with any make if you get a good one you are lucky. I am awaiting new Chevy redesign.No more Fords.
