Ford Excursion :: Losing Power When Accelerate - Codes P0278 And P2623
Jun 15, 2016
I just returned from deployment overseas, excited to get in my truck and ride with the windows down..... Only to find it losing power when I accelerate. It will slowly gain speed but it seems to have no turbo/boost. So I start down the road troublehooting.
I have pulled the EGR valve and it was clean
Checked Map hose, cleaned port on intake
Changed the ICP
Changed the IPR
New Powermax turbo
VGT learn done
New batteries
New DC power 250
Pulled the EBP sensor and cleaned. Even tried it unplugged
New fuel pump
New FICM with Atlas 40 from ED
Truck is 2003 6.0L Ex 163k
New ARP studs/gaskets/
Has a tune but also ran it in stock; no change
Flushed and filled with CAT ELC
Has new BPD oil cooler relocate behind passenger batt
So for my scan gauge numbers....
My deltas are good; 201/196
When I pull out, and normally drive my IPR will do 86.7 in the throttle but ICP won't go above 15-1700. If I floor it the IPR will jump to the 86 but the ICP drops to 700-800 and it's obvious the truck just doesn't have power. It feels like everything is working. Turbo spools and it acts like it wants to roll coal.... But it won't. That ICP drops and she falls on her face.
I ran the SCT code and usually don't get anything except the 1000 which isn't anything. I once got a P0278 and P2623
I even tried another ICP today. The pigtails were clean and I had already swapped them last year.
What else ???? It starts fine. So it shouldn't be the HPOP but that's all that's left really. When I do start it, it starts right away but sometimes will kinda rev or run into the start. Either way of all the troubleshooting steps it seems normal. I just don't have the power.

I have a 2011 F-250 with 112k miles.
On 11/25/2016 at approximately 110k miles: my truck was 100% stock. I was about a half hour into a 3 hour drive and I got a Check Engine Light. I stopped to get some food and my truck was idling for about 10 minutes when the light came on. My code reader said it was for P0278 "Cylinder 6 Contribution/Balance". I cleared the code, restarted the truck and drove away.. I drove about another 5 minutes until I started hearing a real bad air leak and the truck just didn't feel like it was driving right. Check engine light never came back on, but it just didn't feel right so I towed it home.
The truck went to the dealer, they said they found the EGR Inlet Tube was cracked, and that explained the air leak sound I heard when I continued driving, and they said the truck was probably running rich from the lack of air and that set the P0278 code. They replaced the tube and everything was fine.
On 12/14/2016 with around 111,500 miles: upset that just one pipe breaking could take down the whole truck with no one having that part in stock to get me back on the road, I "deleted" my truck. Removed the DPF, installed "block-off" plates for the EGR (which goes in place of the EGR inlet tube), a Cold-Air Intake, and H&S MiniMaxx. (Exact parts can be found in my signature).
On 12/25/2016 with around 112,500 miles: I was getting ready for work and I started my truck using the Ford Factory Remote Start that was original equipment on the truck. The truck ran for about 10 minutes when I hopped in it and took off. As soon as I got in it, The Check Engine Light was on and I had a code for P0278 "Cylinder 6 Contribution/Balance". I erased the code and restarted the truck.. drove to work (around 50 miles) with no problems. Truck ran fine, I never felt any problems, and no smoke or anything like that.
10 hours later I'm getting ready to leave work and let the truck run on remote start for 10 minutes. I hop in the truck and drive away.. there's no check engine light, but, my tuner says there's two DTC's.. P0278 "Cylinder 6 Contribution/Balance" and now P0281 "Cylinder 7 Contribution/Balance"... I cleared the codes, restarted the truck, and drove home with no problems.
12/26/2016 I started the truck on remote start again for 10 minutes. No check engine light, but the tuner says there's one DTC for P0281 "Cylinder 7 Contribution/Balance". Cleared the code, restarted the truck, and drove to work with no problems. Got back in the truck after 12 hours, drove home and didn't get a DTC or Check Engine Light on the drive home.
12/27/2016: No DTC's or Check Engine light. Where I should start looking to fix this?

My truck was running fine, it's stock as far as I know. Shut it off, it sat and cooled off for a while. When I tried to crank it, it wouldn't start, threw 2 codes. P2285 and p 2623. I unplugged the icp sensoran tried to start, no start. Plugged it back in and it started fine for the rest of the work day ( I work out of it). Drove it the next day without any issues. Today went to start before work and no start with the same 2 codes. What should I check first? I don't have any monitor yet. Bought the truck a month ago as a work truck. It has 164000 miles.

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.

Truck all of the sudden out of no where started to shake at idle my first thought was that it is a miss. Then on hard acceleration blows black smoke with NO tune on at the time, plugged reader in and got code P0278 cylinder 6 contribution/balance. I'm assuming it is a dirty nozzle on the injector. Shake/miss clears out at about 900-1000 rpm. Truck as 247k on it. 50k on injectors. Has ported and o ringed heads, studded, and fully deleted, with bullet proof ficm. Would my assumption be correct?

I have an 03 ex with 03 motor. I use torque pro all the time and periodically check for any codes. Well, I got P0278 but no check engine light. It does seem to start a little different than our 05 with 04 motor. It sounds like it just doesn't fire right away or like it turns over and then decides to start. It doesn't make the destinctive sound at the end of cranking when it starts. I hope that makes since. I could tell it sounded different, that is why I checked for any codes. It also seems to run just fine down the road and at idle. Where to start or what to look for?

My son is joining the site as we try to diagnose his first diesel. We checked fuel flow, and the bubble test. We held the valve down in the oil filter and watched it fill up in about 10 seconds and see it register on the dash gauge.
My Scan Gauge say it pushes 180 RPM while cranking, but it only gets about 225 on the ICP sensor and the IPR instantly maxes out at 84. It has thrown a code P2623 for a stuck IPR valve.
I hear a hiccup in the crank, but I'll let y'all listen and tell me. Will post YouTube link of it.
What are the chances of it being just a hole in the IPR screen or bad valve? I'm afraid we have a HP leak and need to do the air test to find it. I've never done that test and barely hear (rock concerts), my son hears but doesn't know what to listen for.

Over the past weekend I had to replace all of the egr gaskets and seals, due to it failing smog. I removed all of the harnesses over the motor, intake manifold, turbo, and oil filter housing. I also replaced the oil/oil filter and also the fuel filters. The truck ran great before I decided to replace all of the seals. When I went to start the truck, it would just crank and not fire. One thing I noticed was that my wait to start light only stays on for a few seconds, where before it would stay on for a while. After cranking on it for a while I got a code P2623 for the ICP circuit open. I have tried unplugging the ICP sensor to see if it would start, but it just cranks over. The truck sounds like it wants to fire, but wont. Should I pull the ipr and ICP sensor?

Everytime i accelerate medium to hard with the CEL on like this it starts flashing and i loose power. Feels like a sputtering (in idle too). Fuel injection system cleaned and was 75% better for 1 week, but now back to same old. Reset CEL and comes back 100-200 miles later. Cam tensioner? Fuel filter? Coil packs? One of my fan clutches is pretty much out, related?
New spark plugs, maybe needs a tune up...supposedly TB was changed, but i have 106K on 1.8T 2001.5 Passat. New oil pump, timing belt tensioner put on. However A/C belt snapped and had to be put back on then tightened to work. Maybe they didn't adjust correctly at shop the timing belt tensioner?

My 2000 Chevy Astro van started having problems whenever I accelerate, hesitating losing speed, and all I can possible tie it to is a new gas station where I filled up which said "May contain ethanol". I think the "service engine light" flashed on for a second but does not stay on.
Could bad gas or the ethanol be the problem? Would getting the problem codes read at a parts place work?

I have a 2006 F-350. I got a code p2623 ipr circuit open. I ordered a new one and currently waiting on it. I pulled the old one and the screen has been replaced already. How often do these valves go bad? Is there anything else I should check?

Our escape recently started loosing its power steering, once the engine is shut off the power steering is ok. Also some times you can feel a pulsing in the steering wheel. I've been doing some googling and it looks like the dealers are replacing the steering columns to fix the problem.
My question : is this the only fix or if something like some contacts being cleaned or maybe replacing a steering sensor of some kind is the fix.

I have a 1999 7.3 with 260k miles. It is all stock with the exception of straight pipe. I got the truck about 8 months ago and have put about 5k miles on it. Have never had any issues with it. I was driving from Dallas to Houston and about 45 minutes into the trip my truck lost power. I was going about 65-70 mph and the service engine line came on and I lost power. It was running rough and was blowing white smoke. I let it sit for a couple minutes and started it back up and ran fine until 30 minutes later. It did this 2 more times on the way to Houston. Oil is good, coolant is good. Not over heating. Threw a code the first time but didn't throw it the other times. I brought it to a mechanic and he thinks it's the Wastegate.

Where I should start? My 7.3 is running but losing all power. Pumping the fuel pedle will get it started and it will run for a few then lose everything again. Should i just drop the tank and check the sending unit and intake and filters first then work my way up?

2003 crank no start, 196k bone stock truck egr still in truck and stock head bolts. Replaced the icp sensor and ipr sensor, both from ford. What happened is I got fuel then about 15 minutes afterwards my truck acted like it was going up a hill and was just losing power and shut itself off. ficm tested 48.5 volts all 8 injectors tested good and there is oil pressure. Had an egr fault code but I'm at a loss.....

I have a 04 F30 4x4 with a sick 6.0 power stroke. It has 230k on the mileage and ran good. I was driving at speed when she started missing like it had lost an injector and loosing power. The RPM's dropped under 1000 so I had to pull over off the highway. When i pulled over and put it in park it shutoff. Tried several times to get to start but after 10 minutes it started up. I drove about 2 miles and it started the same process. This went on 2 more times before I was able to finally limp home the 40 miles.
It never shut off again but ran very poorly. I put a new valve in and when I tried to start it just mad a pound clunking/clacking noise. The repair shop put a starter in it because it had stopped engaging and was going to ruin the fly wheel. I looked at it and it was eaten up pretty bad from trying to get the engine to turn over. So now all it will do is a single clunk and will not turn over. He says it could be a bad injector that flooded a cylinder or blown up in the bottom end. He did take serpentine off and still no go.

this morning I started my 2004 f250 drove a mile and filled up my truck. Then drove another mile and my truck acted like it was running out of fuel. It was loosing power then stalled out and wouldn't start. About five hours later I tried to start it again and nothing. about five hours after that I tried it again and it started up and drove fine.
My thought was fuel filter or the water trap. I haven't had a chance to open the filters up and check them yet. Today while I was at work I got on here to see if I could figure out what was wrong with it. all I could think of was maybe the HPOP went out or the ICP sensor. Could one of these be the problem or was I right with my original thinking and it's just a fuel filter? First thing in the morning I'm going to pull the filters and replace them.
Could there be something else wrong with my truck that I don't know about? Like I said I filled up the fuel tank then it lost power within a mile and stalled out and wouldn't start back up. Then about 10 hours later it fires up and acts like nothing happened.

2004 f450 with 6.0. Was driving down the road when it started losing power like it was starving for fuel. It carried on for about a mile then died and will not start. No codes at all and we put a new fuel pump on but still wont start. Put a rag with gas in the air box and will run but rough.

I have a 2006 f250 6.0. the truck has 101k miles and to this point I have had zero issues. I am having trouble loosing power after running at highway speeds. Once I stop and begin to accelerate the truck looses power for a few seconds ,Belches smoke and begins to operate normally. I had an egr code, so I replaced egr and the problem persist. It is intermittent and does not happen if I stay under 50 mph.

2011 F350 diesel with 10,000 miles. I have been experiencing problems with the truck loosing power, making rough running noise (pinging like an older diesel), and vibrating. As though the motor is bogging down. It usually occurs on small inclines or hills with the truck in higher gears and low rpms. It will also occur running on flat ground 65-70 mph. Had it occur once while turning the truck around in 1st gear and low rpms. Depressing the accelerator will bring the truck out of it.
This problem occurs randomly sometimes a couple of times a week to not at all. Took to dealer and they found no codes and of couse it didn't do it on the hour long test drive I took the mechanic on. However they did say they had two other owners come in with the same complaints, but could not get trucks to repeat the issue. Problem usually occurs in the hotter part of the day, maybe just coincidence. I had seen similar posts with this problem but no conclusions.
