I have a Cummins ISB 350 with CM2150 in my 2008 Discovery 40X motorhome. Right now the engine does not seem to have any power. It will get up to speed, but VERY slowly. Both fuel filters have been changed. IF you step on the throttle, there is NO thrust; NO surge, just a gradual and slow increase in speed.
View 19 RepliesIt only happens on a very Rare occasion.
When Cold, and when I start out as I open the throttle, it suddenly sounds like there is not a piece of quieting stuff on the engine. I mean its like I can hear right into the engine itself.
I back off, It goes away then I dont hear it again for another Month or two.
I have a knock ! (hoping its just an injector) No engine light, No drivability issues 190k Not there at start up, not there right after a drive. any thoughts?

I have seen this pop up on the truck I think 3 times now over the first 4000 miles on the truck.
Usually it's when I'm on the highway around 70mph or so.
It comes on for a few seconds, then goes away. I do have an exhaust / tune on the car.
2016 F350 6.7; ccsrw, 22K on truck (zero issues previously). Stock other than titan fuel tank that was installed at 100 miles.
700 miles into todays trip, pulling trailer, snowing, in 4x4, tow/haul; pulled out to pass, got into it for a bit and got "reduced engine power" error, truck slowed, would not show boost on gauge, wouldn't rev over ~1900. CEL is on.
Pulled over, stopped, checked under/over and didn't find anything. Shut off truck, started back up, CEL is still on, but truck runs OK. Ran for another 20 miles or so and was OK for how I drove it (including boost showing on gauge). Not hot rodding, crappy road conditions (snow). Got on a big hill from dead start and got into it a bit, about 3K same error came on and she went back into limp mode. Same deal, stopped, shut off, back on, was able to keep going. Was only couple miles from motel at that point, so she is on break right now.
Of course I'm 400 miles from home and nowhere near a dealer. I have a code scanner, but nothing with me to pair it with (daughter has tablet with her, ha ha).
Should I keep going or find a dealer/tow/other? If she will keep running "normally" below 3K, then I can make it home as I don't need to horse it that bad on the roads I'll be on.
Truck has had fuel filters replaced on schedule, dealer has done all service work (oil, etc). Fuel filters were done 7500 miles ago.
This trip, was on third tank of fuel. Had just put in 30 gallons at last (big) truck stop about 15 miles before this issue happened, have 50 miles on this tank. That was 30 gallons into 50 gallon tank.
I am having a problem with a 6.7. The truck has 9900 miles on it. It has a dpf delete, egr delete, Spartan tuner and a snow stage 3 kit. The truck lopes at idle but once throttle is applied it levels out but still runs a little rough. Its keeps saying its in reduce engine power no matter how many times I clear the code. If I clear the code it will come back in 2 seconds with out cranking the truck or anything. Rail pressure is telling me 31090 psi and not changing running or not. I have changed rail pressure sensor, and pressure control valve with no result. The green and violet 5 volt reference that feeds those sensors is only putting out 1.2 volts. Put a new pcm in it still the same and now has quit running totally. The codes are P0193, P0335,and P06A6.
View 14 RepliesThe truck (2012 f350 6.7 lb cc 131,600 miles) started fine. Then while i was setting up the defrost i accidentally hit the ac button. Well I then hit it again to turn off. At that point the engine stalled. Which has never happened to me before. I started it back up which took a bit longer to get it to fire. It now says "Reduced engine power" and runs kinda rough. I thought well im at the end of my fuel filters life so why not change it since i had one. Well the. The FF housing broke. After replacement FF housing and filter it will no longer start. I took the filter back off and checked to see if it was cross threaded or sucking air. I checked that twice. Still no start cranks fast and strong. Codes are
P2138 something to do with the gas pedal
P0193 fuel rail sensor A high
P06A6 voltage on circuit A is whacky (paraphrasing here)
P0532 ac pressure sensor low
Getting reduced engine power warning with no other lights on the dash and what is probably causing it. The truck is a 14 f450 cab and chassis model. I had just had it to the dealer for this problem and the check engine light was on and the said there were two sensors going bad on the exhaust so they changed them out and sent me on my way. Well after driving the truck around all day and not one issue it had just decided to set the rep warning again but did not set off any lights...
View 7 RepliesReduced Engine Power warning and fuel leak? While towing our 37 Fiver uphill a couple of days ago, the warning popped up along with the CEL. Indeed, the truck did lose a tremendous amount of power. When I found a safe place to stop, the diesel smell was terrible. Further inspection revealed that fuel was dripping down the side of the engine from somewhere above the oil filter. I limped along another 15 miles to the campground and unloaded the 5<SUP>th</SUP> wheel and brought the truck in to the dealer this morning. They aren't giving many details of their findings thus far. They say that they've talked to Ford engineers and that they'll have to put a dye into the fuel to detect the origin of the leak. They suspect the high pressure fuel pump, but by the time they remove enough "stuff" to get to the pump, they can't run the engine to witness the leak. This is my first Ford in 30 years behind the wheel and my first diesel. After 8k miles on the truck.....
View 14 RepliesI just had the Local Ford dealer perform an oil change. I noticed the motor running a tad different almost right away but put it off thinking it was something else going on. well i get several miles down the road and anytime i accelerate there is a noticeable vibration and little power. I also noticed that both my water temp and EOT were above 200*. I called the dealer and of course the service department had gone home for the day. I will be calling first thing tomorrow morning.
My drive from work to the dealer is well over 20 miles and at 60-65 my water never got above 189 and the EOT never got above 195. so after oil change water temp got to 205 and EOT was at 215 at the max. This is with no load going 55 mph on the hwy. I have a Ford Premium warranty on the truck as well and this is why I decided to have them do the oil change. they have done the previous oil change as well with no issues.
I haven't had any issues with this truck before but last night I pulled out onto the highway and my check engine light came on and a message saying engine power reduced I finally got it to reset after 4 times of shutting the truck off, was wondering what this may be without knowing the code. I tried plugging my edge cts into it from my 6.0 but it wouldn't communicate guess it needs a update trucks a 15 f350 with only 30000km.....
View 2 RepliesMy low fuel light came on tonight. I drove about 2 miles, stopped and shut the truck off. When I restarted it and began to drive off to the fuel station a notice came on that isaid power reduced then a check engine light came on. I was about a mile or less from the fuel station so I filled up. I cycled the key but the engine light is still on. No low power message tho. The power is fine.
I came home and drained the water drain on the filter, didn't see any water but hoped it would solve the problem. I cycled the key a few times and started the truck but the light is still on. My truck is a 2013 f350 6.7 and has 211500 ish miles on it. I bought it a month ago with 18500 miles and haven't had any issue until tonight. My only thought is maybe the fuel filters need changed. I don't know if or when the previous owner changed them.
So I just went on a vacation pulling my horse trailer (first time leaving the state with this truck) and at about 5 hrs into the trip I had a message Reduced Engine Power and went from 70 on the interstate to 10 miles an hour and slowing rather quickly. I ended up shutting it off and restarting and it came back just like normal. I found the nearest ford dealer and they put the computer on it and it showed absolutely nothing, no codes and nothing wrong. The mechanic reset some things and we went on our way.
Then I ended up getting a check engine light saturday. I found someone to read the code and it came up with P164A which is an O2 sensor, he was able to clear it and I put on probably 50 miles today and no check engine light. I have about a 10 hour drive back home. Still debating if I take it to ford near here if they will do anything now that it doesn't show a light?? I hate to chance getting broke down on the highway with a truck that will basically shut down like that?? It just doesn't make sense to me.
I started my '16 6.7 this am and drove it about a mile.
The check engine light came on and at the same time the display said "Reduced Power". I decide to turn around and try to make it back to my shop but shortly after turning around the display said "Low Fuel Pressure" and within a couple of hundred yards it shut down leaving me stranded by the side of the road.....
I called my local dealer who gave me the Ford Cares 800 number. I got a flat bed in about 1.5 hours which I didn't think was too bad considering I live in the country and they brought it to the dealer. The SA said it might be a couple of days before they could look at it as they were pretty busy... What it could be? The engine is stock with 9100 miles on it...
I just had my first fuel filter change (about 9,000 miles). After the shop changed both fuel filters with factory Ford ones, a check engine light came on and a "low fuel pressure" warning, along with a "reduced engine power" warning. It also stalls a lot and takes a long time to restart.
Obviously, they didn't do it right. I suppose there is air in the lines or something didn't go back together correctly.
My '06 seemed to purge itself, but this truck obviously won't. It is not even driveable to get it back to the station, to see if they can correct the problem.
The thing is, I watched them do it, so if someone can ask me the right questions as far as what I saw, maybe I can lick the issue in the driveway myself.
My uncle bought an '05 that stopped running one day. He was driving down the road and engine lost power. He was able to coast into his driveway. Unfortunately, it's been 10 years since I've work on a 6.0 and no longer have any of my computers.
He did state there is no check engine light. He's going to change the filters today / tomorrow. I'm hoping to make it down there this weekend to look at it, but what to look for. Even more unfortunately, we really don't have any specialty tools or gauges.
I have a 2011 Ford F250 6.7 Powerstroke. It has 107,000 miles on it.
The other day I was driving it down the highway and it got a Reduced Engine Power message on the dash. It lost power and I got off the highway to the service road. Then it died on me.
Had to get it pushed to a station then towed home. It wouldn't start. The starter cranks over for a few seconds but engine won't start. Checked all the fluid levels and batteries. My DEF fluid was only a half gallon low.
What I have noticed is that the DEF level indicator hasn't reminded me that it was low for over 4-5 months now. I had been putting in about 2-3 gallons every 3 months or so. But it hasn't reminded me lately and I just forgot. This is my first diesel.
My 2011 6.7L F250 Superduty died on interstate the other night. Picking up throttle pulling onto interstate when a message came on the dash "reducing engine power" and the truck died. It will crank but will not start. It will start on ether but dies when that runs out. Has the following codes... p1249 Wastegate control valve, p0087 fuel rail/system pressure too low, p1291 & p1292 injector high side short to ground or battery (bank 1 & 2), p2291 injector control pressure too low-engine cranking. The codes are telling me I don't have enough fuel pressure but scan tool says I have 4000 w/ key on and 6370 while cranking and I thought 5000 was the pressure needed.

My family and I were driving into West Virginia this morning when the reduced engine power message came up on the dash and the truck died. I coasted off to the side of the road as best I could and got out. Immediately I smell diesel fuel. I look under the truck and there is fuel all over the passengers side frame and when I keyed it back up fuel started spraying down by the right front wheel.
Pulled the fender liner back and saw a small rubber hose that looks like it came off of a tee fitting down by the egr components. I tried to get it back on but wasn't able to get it seated 100% and when I tried to restart it blew off again. Truck is completely stock and ran perfect right up until it died.
I have a 2011 6.7 F-350 Diesel. I bought the truck new and I've never had any problems with it until now. I have a SCT Chip & Tuner. It needed an update so I returned the truck to stock and a code came up on my dashboard that said "reduced engine power" which obviously I thought was Normal because of the modifications done to my truck.
I updated my tuner and returned the truck to a performance tune but this dashboard code will not go away. My truck isn't reading any codes and there's no other indication lights on. The truck has Normal RPM readings but 0 throttle response. No power at all...
Was driving to Oklahoma this morning everything was fine, got to the location of where we are working and check engine light came on and stated reduced power, tried running a health report and it wasn't working?
View 1 RepliesI have a 2012 F-250 6.7L w/8K miles. I have been struggling with this issue for 6 mo. The engine feels like its missing at low RPM. I would equate it to the feeling of a bad coil pack in a gas engine. The boost indicator drops to 0 for a split second then recovers. The dealer says they can't find the issue but went ahead and replaced the turbo. After the turbo replacement It got worse. This is an intermittent problem with no codes.
