Ford Super Duty (1999-2016) :: 2000 F250 Miss Only At Idle
Mar 27, 2017
I have a 2000 F-250 V10 that misses (cylinder 10) at the idle, once you give it gas it runs correctly again. I am at a loss. I have replaced the plug, tried moving coils from one cylinder to another to see if it shifts the miss, and it has new injectors. What this could be?

Question, my truck started to have a miss under normal acceleration, when I really get on it, it clears up? I also noticed a bad sulfer smell at idle. Im thinking the cat is possibly plugged? Truck had 172000ish on it, and the cat is original. I did do a big tune up this past fall, new plugs, coil packs, air and fuel filter. Should I put a new cat on it? And a new oxygen sensor?

On a 2000 F-350 with 5.4 engine, where does the vacuum line enter the cab? I got a truck in with no vacuum signal to the heat controls, and it has a slight miss at idle. Both of these are signs of a vacuum leak, but i can not find the line going into the cab.

I have a 2000 Ford-F250, V10, 6.8 liter Gas. The issue is that when I try to start the vehicle it will start, but then start to idle real low and then die. If I try to restart sometime it will and sometimes you have to let it sit. I can also pump the gas and it will sometimes start.

Got a 2001 F350 diesel auto, 295k miles.
It has miss when over 2000rpm. Below 2000 its smooth.
ICP has oil in sensor, ordered new one. Gonna change oil too.
CPS is new (not sure if its black or the other one). Starts idles and drives good otherwise.
Where should I look?

I have a 2000 F350 cab and chassis 4X4 with V10 and a 5 speed manual (actually it's a 4 speed with overdrive). My problem is the engine seems to have a miss in it. When I first start it in the morning it usually runs good for 5+ miles till it warms up then if I am not pulling a load I can hear what sounds like a miss but the truck accelerates fine. If I am pulling a load I can also feel a slight steady consistent shudder and I can tell the truck doesn't have the power it should and the gas mileage SUCKS worse than it use to.
I ran a bottle of Lucas deep clean through a tank of fuel and that seemed to work a little but I will still encounter the problem sometime during the day. When the miss seems to be gone I can hear a very slight pinging noise when I accelerate or pull a hill with and/or with out a load. The pinging noise I hear sounds like an engine with a distributor that is getting to much spark advance if you have ever experienced that before.
I purchased this truck used several years ago and I don't know what the PO did but the check engine light is not coming on and it doesn't throw a code. I put 10 new ford coil packs on it about a year ago so I really don't think it's a coil pack, but I could be wrong. To me it sounds like maybe it an injector problem????? I know there are several sensors on this engine and I am thinking maybe a crank position sensor is not working right but I honestly don't know???? Is there a way to test this sensor?

My 2000 F-250 6.8L V10 has a choppy idle during the first 30 or so seconds after a cold start up in the morning then it smooths out and drives perfectly. If I were to place the truck in gear during the choppy idle, it would not die and throttle response would be fine.
I cleaned the MAF sensor and checked the PCV elbow for cracks (no cracks). It idles at about a 1000 rpm during a cold startup then drops to about 750 rpm according to the dash tachometer. The truck has 187,000 miles on it.

I have a 2003 f250 5.4 with a couple of bad valves and low compression and a dead miss because of it... I just bought what appears to be a 2001 5.4 from an f150... I am worried now this engine wont work and cannot find anything online that can tell me yes or no....

I have a 2001 Ford F250 V10 with about 70,000 miles on it and now the gauge indicates low pressure when my warmed up truck idles around 1000 RPM.
I went off road the other day into some mud and since then I have had my oil pressure gauge reporting low at idle and normal when moving.
I was a quart and 1/2 low on oil which I filled and the next day I changed the oil. I then had taken it Ford shop who replaced the oil sensor and said all fixed. It wasn't and I took it back in ... now the mechanic indicated it is probably the crankshaft bearing based on his experience and I should replace the engine.
This seems drastic? Wouldnt' the next step to go check/replace the oil pump?

I have a 99 f250 sd with v10 that has no power. Will crank, idle and die sometimes. Getting codes p0351 - p0355. No power when driving.

I recently purchased a 1999 6.8L. Runs great when cold but after warming up the idle gets rough. Truck has new plugs and coil packs and fuel filter. Checked the fuel pressure and the idle is right at 30 psi. I read that the good pressure range is 30 to 45 psi. Is 30 psi acceptable or should I replace fuel pump or regulator? Any next step to solving my idle woes.

Having problems with no heat at idle or low heat in the cab. I just bought this truck a couple weeks ago and have a limited warranty on it. The truck makes no heat at idle. I start it and let it just run, engine temp gauge goes up to normal operating temp in 15 min or so, still nothing from the vents but cold air. If I drive it I get a "little" heat, at idle, cold air again. I believe the thermostat is working because like I said, engine temp stays right in the middle.
Brought it to local ford dealer, their diagnosis was heat core clogged and needed to be flushed, had that done. truck has been running 40 minutes in the driveway now, engine temps nice and warm, no heat. What could be the issue? I took a picture of what I believe are the lines running to the heater core, just barely warm to the touch, not hot by any means. It looks like there is a vacuum actuator on the line running in but there is no hose attached to it, what this it, should it have a line running to it?

I am new to the v10 I only ever owned 7.3 this is my father truck it's a 99 with 200k on it. The problem is it will idle fine when cold but when it is warned up very ruff idle no codes and when I go back at the end of this week I will check the O2 sensor with AE but I really don't know much about it.

I have a 2004 F-250 with a 6.0 and a 6-speed with 140,000 miles. It has been studded, and has upgraded injectors. ( Not sure on the size, they bored them at at the diesel shop that studded my heads.) Also have an EGR delete, with the EGR turned off on the SCT as well. I also have a SCT Livewire set on the 65HP tow tune.
Truck has always ran great in the year and a half I have had it. I changed the oil three days ago, and now I am getting a miss at idle. The trucks cranks right up and drives normally. Once it is at operating temperature, when I stop at a light it has a very noticeable miss. There is no surging, or change in RPM's at all. Just seems like it is cutting out every few seconds. This is also somewhat intermittent. FICM shows 49 volts always, even when this is occurring.
Also, this may be unrelated, my oil temperature seems higher since the oil change. Was around 192 water/197 oil while cruising 70 on the interstate. Now, its' more like 192/202. I've always ran Motorcraft 15w-40, and that is what I used for this oil change as well.
I see some people have a similar problem, but all the posts I've read involved fluctuating RPM's or surging, or both. Other than this, the truck cranks and runs just like normal.

2000 f250 7.3. Today I tried using the 4x4 and no light or anything. Here is what i have tried so far. Swapped the relays and also swapped them with the towing relays with no change. Not getting any voltage to the t-case shift motor at the selector switch testing between pins 2 and 3 there is 4.3 volts with switch in 2wd 2.4 volts at 4 high and 1.09 volts at 4 low. Where to go from here? it worked fine 3 days ago.

My 5.4 had a bad miss several months back with no cel. It would barely climb hills it never even needed extra throttle on before (3rd gear, wide open, 35 mph, etc). Ford dealer ran a scan and it had two bad coils and plugs. I changed those and it ran much better, but still had a "pfft pfft" exhaust leak type sound at idle. I checked the exhaust studs and they were all good, so I wrote it off as just a normal exhaust leak.
Full throttle in 5th gear to maintain speed limit when normal throttle before was sufficient. I got home and parked it and it sat over night. I went to start it today and it died. Tried again, died again. It only stays running if I am pressing the gas and I hear a fluttering or air sound of some kind coming from the passenger's side of the engine. It doesn't cut out or miss like a bad coil or plugs, but like you choked off the air supply.
All plugs are still in place, exhaust studs look good, tried it with the air box unhooked to see if it got clogged, and going to check intake leak tomorrow...

I just purchased a 2012 F250 XLT with the 6.2. It has 38,000 miles on it. Yesterday I noticed, when coming to a stop, the idle will sometimes drop below 500. The engine will stumble a little, then the RPM will jump up to 1,000. Twice it has stalled on me. When it stalls, the engine will restart just fine. No codes in the computer or warning lights on the dash.
I will be bringing it back to carmax, as it is under their 30 day warranty still. Hopefully they will be able to figure out something. I am thinking either the TB needs to be cleaned, or there is an issue with the canister purge valve. I saw the TSB for the CPV but it doesn't cover my truck.

I have a 99 f250 5.4l 2v with 165000. just two weeks ago i went to start up the truck on a job site to take lunch and it was running really rough. I talked with a mechanic at my shop and he said that it sounded like the aic or that i needed plugs. I went and bought aic and plugs and installed them all in one day. I unhooked the battery before i did any work and have changed the coil packs about 3-4 months ago when it was jerking at highway speeds. I am at a loss.
Read so much on the site about could be this or that and cant afford to through money at it like the govt does. I replaced the ait(air intake temp sensor) and the ect(engine coolant sensor) after i got a code from oreillys that said p0113 which is high input on it. I have read it can be so many things and it seems to be running rich because i am getting about half of mileage i was getting before problem started. i need a fix soon as i must drive the truck to work everyday which is a 52 mile trip total.

I have a 2001 f250 with the 5.4 I replaced the belt because of belt squeal and after replacing it the squeal is gone. now after the truck gets to its normal temp and I stop at a gas station for dip I will leave it running and when I come out it has this loud chirping noise it kinda sounds mechanical but it very well could be something on the belt drive. I am stumped it goes away after I start driving but I am kind of nervous about what it could be.
And the only time I hear it is while the truck is at normal temp and in park I have rolled the windows down and can not hear it while driving or at traffic lights. a part of me says it could be the fan clutch and now that it has a good belt on it I am hearing a sound of maybe the clutch going out or a pulley bearing starting to go out. Where I should go from here?
