rough idle

So we've been having some troubles with my dad's '03 6.0 running terrible when it gets warmed up. It starts up great when it's cold (it was ~15* last night and she started right up without even being plugged in). Drives fine, plenty of power, only a slight shake/miss at idle. Once it's good and...

After replacing the injectors today I still have a code and am hoping someone will kindly help to guide me in the right direction by lending their experience and insights. Original Codes: and P1293 (High Side Open Bank 1) and P0273 (#5 injector circuit low) Initial Problem: Rough idle and...

Next stop is to the shop tomorrow if I can't get this thing going, i'm hoping for someone who can take a look and point me in a new direction. Initial complaint: out of the blue truck started one day w/rough idle/timing seemed to be missing, check engine light on. Complete lack of power, enough...

Hey guys, I have a very strange issue going on with my 6.0 that I need some help with. Let me start from the beginning. A few months back I started having a misfire issue with no codes so I decided to go ahead and re-seal injectors. I was in a time crunch since this is my daily driver so I...

Hello I am new on this page and finally broke down to get some help with my 2006 F-350 6.0 PowerStroke with 152,000 miles. It has head studs, EGR delete, 4 inch straight pipe, AEM Intake, and an Edge performance system and 58v ficm. Recently I did head gaskets on this truck and before starting...

I'm kind of new to power stroke. Been an experience so far. Lol. I have a od problem I can not figure out. When I first start my truck, it runs rough. It like it's running out of time. But if I let it run for a minutes, shut it off, the start it back up, its smooth and like a new truck. I notice...

Hey there! So I have a 2003 F250 that hasn't been running smoothly lately. The main issue is when I'm idling, usually in drive but occasionally while parked too, the truck seems to miss/stumble a little bit. It'll sorta bog down into the lower RPMs and act like it wants to die. So the RPMs seem...

Hi All! Been reading great stuff on this site for years. First time i speak up! Stranded after driving my 99 7.3 8 hours. I ran low on fuel pressure all of a sudden. Got towed to a Hotel. I have Wife and 3 kids with me and it's around 0 to 15 during the day. i Replaced the IPR to get pressure...

I have found lots of posts chasing around various issues with Loss of Power & Rough Idle. I have read all I can find hoping for an answer but as of yet I have found none, with the possible exception of either 2 bad injectors or a shorting Fuel Injector Harness. My Story: 2003 Excursion with a...

Hello all, I was in the market for a truck and had the choice of many clean, mid mileage perfectly running ones but for whatever reason took the risk on a repo 2008 F250 6.4. The truck is "clean" and has a clear title but has been sitting a while and has high mileage. I got a key programmed...

I have an 05 Excursion with (per mechanic) 04 6.0. Had no.7 injector code come up. I was also dealing with stiction, so I decided to replace all injectors and upgrade to the 155's. Now on decel from around 50mph to 35mph when the load drops to 0.0, then builds back up, there appears to be a...

Hello all, I have been having an issue with my truck that has been slowly progressing for years and Im hoping someone can help me identify it. At idle my truck will shudder and shake a bit. Sometimes aggressively, sometimes not. I would think it just has worn/dirty injectors or something but...

So I bough this truck, 2004 F250 6.0 and it had what I was was told was a bad turbo. White smoke out the tail pipe with a slight rough idle, and did stall a couple times. Against my better judgment I spent the money and replaced the turbo even tho to me it looked more like a bad injector. The...

Hello all. I have a 2001 with 280,200 miles on the original injectors, original HPOP, IPR and ICP. I have a noticeable but not bad miss (or something) at idle, in gear or not. It comes and goes, does not matter whether engine is warm or cold. I do have injector hammer from #8 that I have...

I bought I 2003 Ford F350 lariat 6.0 and it started shaking when it got into over drive really bad. I ended up taking it to the ford dealership where I live and they ran so tests and told me that I had three injectors bad 1,4,6 and my egr valve was bad and so was my IP sensor which am assuming...

I am now to this forum. I just noticed that my temp gauge is not moving past the first notch. Looked at coolant tank and it is low. When the truck starts to warm up it runs/idles rough and loses power. Can a bad/stuck thermostat cause this?

Hello all, I have an 01 with 265K miles still original HPOP, injectors, LPOP. I have a pretty pronounced miss, shake or something going on at idle, whether in or out of gear, hot or cold. I have done the Hutch/Harpoon mods with an external Racor filter. I changed both fuel filters last night...

My late 99 F250 has been acting strange lately. It has been idling around 900 rpm even though outside temps have been around 80 to 90 out. When i go out in the morning to start it, it runs fine no strange issues. Once driving for a bit when i come up to a stop my rpms will drop to 900 or so, but...

my late 99 7.3 has some strange idle at random times. Fires right up runs fine cold/hot. But sometimes after driving for a little bit if you sit for a little while weather you are in gear or in park, the idle with bounce. Its not dramatic but you can see it on the tach, it will jump up and down...

A friend of mine has an 06 f350 6.0. The truck has been running very poorly... No power, very lagy, sounds really rough. Today the truck stalled on her while driving it. It would start back up after cranking a lot longer than usual and idled rough, the longer it idled the rougher it would sound...
