Ford Super Duty (1999-2016) :: P0300 Code And Various Misfire Codes For Random Cylinders

New plug on right, lower bank 2 plug on left

Started getting a P0300 and various misfire codes for random cylinders. Truck has 95,000 kilometers so figured I would change the plugs. Several of the plugs on the lower bank on both sides were pretty much toast. Most of the plugs on the top looked good. All of the plugs had a small deposit where the spark hits the ground probe. Picture is typical plug from lower side. changing the plugs should make a big difference in how she runs and eliminate the codes.

Took right on 4 hours same as dealer said it would. I would have got it quicker but it was not a race.

Ford Super Duty (1999-2016) :: Losing Power - Random Misfire With No Codes?

99 F-250 SD 6.8 had an issue with it while moving from Del to Phx, Az. Found collapsed air cleaner element. It looked like someone stepped on it. I replaced it as well as the MAF. This fixed the issue. This was 350 miles into the trip. The truck seemed to be down on power as it didn't want to pull my trailer up any type of grade except with OD off. Around 2K miles into the trip in developed a random misfire with no codes. I am at my final destination and the misfire is worse. I am not showing any codes at all or pending either. It is a bit toasty outside to be out there diagnosing issues, and I won't start changing parts randomly either. I have a NGS scan tool with the proper cards.

Ford Super Duty (1999-2016) :: E350 7.3 - Vibration While In Park At Certain Idle

My 99 7.3 has had a vibration / shake in cab as you rev up while in park in neutral around 1000 RPM -1700 mostly. Around 1500-1600 is the worst. At idle it seems fine and what you would expect from a 7.3 but then as you give it higher idle, it starts shaking cab and you can physically see seats start shaking and it all feels rough. It also translates to a vibration while driving in those RPMS down the road... It has new injectors, transmission/ torque converter, HPOP, exhaust and a whole lot more.......

Ford Super Duty (1999-2016) :: 2015 - High Idle When Cold?

I'm going to cut right to the chase, when did ford stop having the diesel high idle when it is cold? I have a 2015 350 I bought last August and assumed it would high idle like previous power strokes. I even put a ts6 chip in my 97 just for high idle option to keep the motor warm when idling around our farm. I realize ford probably doesn't want trucks idling long because it kills mpg and isn't good for the emission system but to be honest I could really care less about mpg as long as it's decent and a high idle would keep emissions pushed through. Is there an option or anyway you can get the 6.7 liter to high idle?

Ford Super Duty (1999-2016) :: Loud Knocking At High RPM And At Idle

I just got a 2003 f250 5.4 triton and it has a terrible knock. I've hear of the cam phaser problems but this thing knocks at high rpm and at idle so I doubt it would be a phaser, I thought it could be a rod bearing but I'm not losing any oil pressure. Its a pretty loud knock I don't have money for a mechanic to diagnosis it...

Ford Super Duty (1999-2016) :: F550 V10 High Idle Up To 1200 Or So

I have a 1999 Ford F550 with a 6.8L V10 and a 4R100 Auto.

I want to run an underhood hydraulic pump, like what a wrecker uses only I want to use it to run a generator under the truck.

How can I get a 6.8 to idle up to 1200 or so? I searched the Body builders guide and it looks as if the idle up is for the 7.3 only.

My truck also is not a 2005 and up like the other posters, who can take advantage of a drive by wire.

Also I doubt my transmission has a PTO cover so I think a generator option using that route is a dead end. What are my options to idle the truck up to 1200?

Ford Super Duty (1999-2016) :: 2013 F350 6.7L - High Idle At About 1000 RPM

New too my Ford, but anyway it's -10 Celsius. My trucks been idling for a few hours and probably will all day because of my job. Usually idles about 600rpm normally. So today the oil temp was about 80degrees Celsius. Then the truck idled up too about 1000rpm for a while. If I touch the gas it goes back to normal idle speed but then starts idling up again after 30 sec. What temp does the truck want too keep it at?

Ford Super Duty (1999-2016) :: 2004 F250 - Code P0401 EGR Flow CEL

I've researched the heck out of P0401.... I have an 04' F250 w/a 6.0, 61k miles, completely stock. I have been getting a reoccurring P0401 EGR flow CEL. I've checked all the fittings and tubes and see no cracks or breaks. I've checked the exhaust system and no signs of leaking soot anywhere except on the passenger side exhaust manifold, there is some minor deposits of soot near the first two cylinders, but that's it.

Everything else looks good and I can't hear any hissing either. I am not getting any white smoke from the exhaust. I pulled my EGR valve and looked at it, it looked fine. I cleaned it off and put it back in. Then I got a new one just to see if that fixed it. I am missing a little coolant. I'm adding maybe a few cups of coolant every few weeks. Truck is always serviced and only repairs was Ford replaced the EGR valve in 2008. When I pull my EGR valve, it is slightly moist in the housing but not wet and no sludge. Again, the EGR valve had a nice layer of soot, no build up or sludge on it....

Ford Super Duty (1999-2016) :: 2015 - Creating High Idle Using Up Fitter Switch?

I hooked up one of my upfitter switches in my 2007 F-350 diesel.

I would like to do the same thing in my 2015 F-350 diesel truck.

I would like to use it to attempt to get the truck warm before use as I am experiencing poor heat characteristics in this truck.

Ford Super Duty (1999-2016) :: 2001 - Suddenly High Idle / No Blower And Hard Shift

My '01 recently seized up and a buddy determined it was the AC pump. Replaced the belt with the bypass version. A month later, I moved across the state to Iowa. A couple weeks into living here I turned the truck on and it was idling really high (about 2500-3000) but would settle down to around 1100 when put in gear. However, shifting into gear is causing a progressively worse "jump" into gear. Hadn't really had the money or the time to take it in so I let it mostly sit unless I absolutely needed the truck.

Today, the idle is still high and does seem to cycle a bit in that it will rev up close to 3000 then settle back down around 2200 or so and then rev back up again and so on. I backed it down the drive into the sun for a little warmth and it darn near jumped a foot when I shifted. I turned the heater on defrost so I could clear the windshield and absolutely nothing came out.

I can't get into a garage for a few days to get it hooked up for diagnostics. So I thought I'd try here. My research leads me to think part of my problem may be a vacuum leak and/or maybe a sensor somewhere.

Ford Super Duty (1999-2016) :: 2010 F250 V10 - Lost All Power - Code P0300 Came Up

I have a 2010 F250 with the V10 and 42000 miles. Lost*power*while pulling a trailer. Couldn't get over 30 mph. Tried turning back home and lost all*power*and would barely idle. Fuel filter good air filter good. Code P0300 came up. Towed it back to the house and then couldn't even get it to idle. Wouldn't throttle up past about 2800 rpm. Cleaned MAF sensor and nothing. Somewhere during all that P0174 code came up and misfire cylinder 10. Cleared codes and they haven't come back. Now when trying to crank, it barely turns over, yet battery is good. Opened air filter cover after getting it to start one time and there was some light smoke coming out. Also while barely keeping it running for a little bit, the catalytic converter on the driver side was fire hot and the other side I could grab with my hand.

Ford Super Duty (1999-2016) :: 2003 F250 - Service Engine Light Keeps Popping On And Putting Out Code P0401

I just bought a 2003 F250 from a used dealer. Unfortunately the service engine light keeps popping on and putting out the code P0401, I have replaced the EGR, cleaned the inside, and cleared the code. However it continues to keep popping up and then it will turn off after a couple of days. I mostly drive in the city and the code generally only pops on when I drive on the highway. I have also noticed a lack or delay of power, when I really hit it hard, I think its because the computer is keeping the egr valve open. What it could be?

Ford Super Duty (1999-2016) :: 2010 Truck Stuck In Regen Cycle - High Idle And Increased Exhaust Smell

[URL] ....

The problem with my truck is not that its regen'ing too often, the problem is that its STUCK in regen cycle. For the past 4-5 days my truck has been going into regen about 1-2 min after i start driving it, every single time i start her up. If i start my truck in the morning and let it warm up for a few min, i come out and my truck is idling higher then normal and has an increased exhaust smell, but when i aply the brake the idle goes back to normal. Then i start driving up the street and BAM "cleaning exhaust filter" message comes up and the and immediately the sound of the exhaust and induction changes and it sounds like sputtering/knocking.

Sometimes the the engine will flutter in decel or shutdown. HORRIBLE gas mileage, Reduced engine response and power, and white smoke is cooler temps. Basically all of the normal signs of a regen cycle, am i wrong? Im pretty sure its either a dpf sensor or possibly something wrong with the DPF? I haven't had one problem with my 2010 besides an egr valve and she has 167k miles and is completely stock and im very happy with my truck! 2010 6.4L

Ford Super Duty (1999-2016) :: Random Plugs Under The Dash?

I need to identify these random plugs under my dash. I think they might be for some sort of alarm or remote start unit and they seem to be tapped into the ignition wires. Suspiciously like remote start plug wires but I can't figure out what unit they would be for?
