Ford Super Duty (1999-2016) :: F250 Started To Surge When Driving Down The Road
Jan 29, 2015
I have a 99' f250 I purchased a few months ago. Here's what happened. Today I was driving down the road and it started to surge. I pulled over and shut the truck off. When I went to start it, the motor turned over slow for a sec and then clicked. When I put a jump pack to it, it fired up. I took it home with the jumper still hooked to it and checked voltage. The alternator was throwing 33.4 volts!! I went to the auto parts store and bought a new battery and alternator. Now the battery shows 11.7 volts steady. The alternator still reads 33.4. Also, if I unplug the positive lead while it's running, the truck shuts off. And one more thing. If the key is off and I reconnect the positive lead, I can hear the fuel rail pressurize. What is going on? I hate electrical gremlins.

I've got a 99 f250 5.4 that runs like a top. In the last 6 months I've been chasing a little problem. It doesn't happen all the time but seem to be happen more and more. While driving any speed If I let off the gas the RPM's hold at around 1500 then surges down to 1000 then back up again to 1500.
Does that 2 to 4 times then all good. Give it gas again it does it again. It kind of does it when it wants. Could be fine for a trip around then next trip it acts up again. Checked a lot of the vacuum lines, PVC valve and replaced the idle control next to the EGR valve. EGR is next.
Idles and runs fine except the surge thing..
P0401 code as well.

While driving down the road the truck will just cut off. We wait a few mins and start it again can drive a few miles and it cuts off again. we have replaced the ignition coils and it is still doing this. No codes are coming up to get any idea what it can be?

This morning while driving cold a fuel leak started on my truck it's a very heavy leak wondering what are the most common leaks on an 2003 F250 6.0L are so I can start there.

I just got 03 f250 with 6.0 and when shifting has a weird surge/lag thing happening. Reminds me a little of the old 7.3 surge when it was just started on a cold day. Seems to be worse in higher gears.

I have an 03 with a 6.0 diesel, going down the road and started losing power and then died. Won't start, and I don't have a scan gauge. Several sources said ipr valve, and from videos on youtube I thought may be a good place to start. I bought a socket and pulled the valve, to check the screen. There is no screen whatsoever on the ipr. The oils clean, as I had changed it about 200 miles ago, and I ran a magnet in the hole looking for a screen, couldn't find anything so I used my fluid pump in the hole. No trash, screen or anything. Do some ipr valves not have screens? What would be my next step??

01 F350...4R100/V-10/4wd. Sometimes get a vibration driving down the road. First thought of tire out of balance but then the vibration goes away and may not come back for a few days or more. It starts sometimes around 30-40 mph and stays all the way up to around 65 mph. Even slowing down it vibrates or shakes. I can stop and take off again with nothing happening. Would think tires out of balance would do it all the time. And a few times....pulling my 5th wheel...making a right turn out of a parking lot.....it feels like a rumble from the rear.

It's an 02 f250 4x4 crew with 7.3, 6 in lift and 35 in tires. It has all ways wandered a little bit and I just accepted it. I changed everything in the steering from ball joints, tie rods and drag links less than 2000 miles ago. Everything still seems good and tight. Recently it has gotten a lot worse so I checked again and everything seems to be tight. Where to or what to check next? It's to the point I don't feel safe letting my wife drive it and I don't enjoy driving it.

I have a 2004 Ford f250 6.0. When driving it down the road i will hear a loud spinning sound, sorta like putting a playing card in your bicycle spokes. The sound can be heard until I make a complete stop where at that time the sound stops and a clunk can be felt. After that the truck sounds normal. This also only happens once between starting the truck and turning it off. I took it into the shop and they could not hear the sound, all they said is i need new ball joints.

A few weeks ago, my employees were driving home one of my work trucks, a 2001 F350 7.3 4x4 Crew w. 130K miles. They were on a straight road in a small town when the steering went completely out. The truck veered into a telephone pole. No one was injured. The truck has major damage to the front passenger's side.
I finally got the truck back to my shop today. It is quite evident what caused the problem. The gear/splined shaft that protrudes from the steering box and is connected to the pitman arm sheared completely off.

2004 F-250. 6.0 I was driving down the road when the engine dies. It was like I had turned off the key. When I tried to restart it, it was no click, no starter sound, nothing. The glow plug light remained on, even while turning the key over. What could cause this?

I have a super duty with the 5.4 in it. it just quit while off road n wouldn't start back up. pulled it back to camp, wiggled wires around cam n crank sensors n it fired up n stalled numerous times then just wouldn't even fire back up. loaded on trailer n brought home, buddy put his tester on there n said there was no rpm reading so I replaced the crank sensor, it fired up n stalls still. wires seem to be good to crank n cam sensors. don't have a manual to tell me what relays are what.

I have a ford f250 with a 5.4l 2v engine and lately it started to shake when it idles. i have changed all the ignition coils and spark plugs, the injector are fine, but i cant seem to pinpoint the problem. the weird thing is that there are no codes. the fuel trim on bank 1 is around -8 and bank 2 is at almost positive 20 and higher.

Have a 06 f350 just rebuilt the engine. Started up ran it down the road a couple miles and lost low side oil pressure. Got back to the house and will not start again so put a gauge on and it only has 3 lbs after cranking for 10-15 sec. Pulled the balancer and lpop cover and front cover had some deeper scoring then before. No noticeable stuff in the pan or filter. Changed out the front cover and lpop. Still has only about 5 psi.

I have a 2001 f250 superduty 7.3L diesel and my air conditioner just randomly started blowing HOT south texas air. I tried to recharge it with refrigerant but the gauge said that it was over charged as soon as I plugged it into the low side port. What is wrong???

2003 f250 5.4 86000 miles. When I start the truck, "especially after it sits a day or more" it starts to fast "Rushes". Like the gas pedal is all the way to the floor. I have taken it to the Ford dealer and they say they can find nothing wrong. They say all fords start up fast but I know this cannot be right. If I start it and let it run awhile then start it again it starts much slower. It only rushes like that a second or two and slows down. Today I noticed that when it started all the gauges pegged out. The speed indicator went up past 100mph sitting still in park. Then they all dropped down to zero then back to where they should be.
