Ford 7.3L Power Stroke (1999-2003) :: Slight Pinging Sound At Low RPM When Climbing A Steep Hill
Was climbing a steep hill at 35 mph just before truck down shifted to 2nd, I was hearing a pinging sound. Sounded like only I cylinder was doing so. What it could be. I am currently running a 1/4 tank of Fppf fuel injector cleaner. Is this a injector noise. No knocking just a slight pinging.

I have a 99 explorer that stops blowing air when I get on the gas or climbing a hill. The motor is still blowing but it stops air coming out the vents. What could be causing this? It works fine other than that.

I have 01 F550 6spd 4x4. sounds rhythmic, smooth at idle but just over 1200 is a pattern surge but doesn't sound like one cylinder, cel is off, ICP and pigtail changed as it was leaking , no change. From what I've read duty on ICP and IPR should be about same % I've included the codes I've gotten, I have the epc disconnected right now as I thought it was a wastegate issue, checking the ICP plug next,anything I've missed? It had a cyl 8 contribution at idle which I hear is common? Will changing CPS work with that one? Think it's a grey one. There's no water in bowl I replaced filter, since replaced ICP, pigtail, and bleeding fuel bowl and new filter the codes are gone but still misses, will be checking uvch, injector buzz test showed no faults. Old diesel guy said to flood with Stanadyne fuel treat?
View 9 RepliesFord Super Duty (1999-2016) :: Vibration Mostly Noticeable While Under A Load Like Climbing A Hill
My current 08 duty was bought with what I believe to be a procomp 6" lift modified to an 8" lift. The 100 mile drive home after buying the truck showed a tiny "hop" in the rear. I ditched the 37s for some new 35s. Still a tiny hop, mostly noticeable while under a load like climbing a hill. I pulled the rear driveshaft and had it fully rebuilt with a new carrier bearing as well. Still gots the hop? The truck has a carrier bearing drop bracket but I think it may be insufficient for the lift.
The rear driveshaft still has a slight bend in the middle of where the two driveshaft pieces connect. Are the 2 piece driveshafts on your 8" lifted trucks sitting straight with each other or do they have this bend as well?? I am thinking if I get a bigger drop bracket it may cure this slight hop I have? Lots of lifted trucks where I live but they are dam near all shortbox with 1 piece rear shafts so I haven't been able to find one to compare. By the way, my truck also has pro comp rear traction bars..

99.5 7.3. 201,450 miles, Just developed a new noise. Was on interstate, in cruise, 65 mph, started while pulling a hill. Kicked it out of cruise and noise went away. I have found it will repeat just pulling a hill at highway speed.
Now for the noise....it almost sounds like lightly opening the secondaries on a gasser 4 barrel. I don't see anything unusual under the hood.
Ford 7.3L Power Stroke (1999-2003) :: Sluggish / Slow Response On The Road - Throttle Surge
7.3 2001 model starts ok at 32-35 F. Feels a bit sluggish / slow response on the road. Reach a hill after 3-4 miles. Engine temp then beginning to go above low level mark. 100 meters up the hill, going around 30 mph there is a sudden surge in the throttle although my pedal is steady. Going back a few minutes later, on flat ground at bottom of hill and with no accelerator pressure, the engine suddenly stalls. Starts fine again after I stop. The same history actually repeated on two separate days recdently on the same hill. CPS is recently replaced. Had some jerking before that, but not the behavior explained above. Current CPS is Delphi light grey. Recent fuel filter change and oil change as well

I just got my new up pipes put on as well as a 38R and pulling a hill hard my truck will hit about 22 psi then drop off slowly I have an electronic boost fooler wich has been on the truck since new pretty much but I don't get a CEL at all is this what I should be getting and I was on the 80hp tune? I ordered new boots and plenum inserts they just haven't got here yet. I know I had a leak before on my old up pipes because they rattled every now and then and I could see exhaust coming out of them when it was cold out but I could hit about the same 22 boost with my old setup. So pretty much nothing changed boost wise except it gets up to boost faster now. I would say it's defueling but I was always told the CEL would come on if that was the case.
View 13 RepliesFord 7.3L Power Stroke (1999-2003) :: Idle Surge When Tuned / RPMs Drop To Around 621 - 630 Then Shoot Back Up To 660 - 675
Recently I have noticed that when on a tune other than stock I am getting a surge at idle - my RPMs drop to around 621-630 then shoot back up to 660-675. On my stock tune my RPMs stay around 640-667 and don't cause the surge (felt as a shimmy so to speak). Is there anything else that causes a similar symptom? I attribute it to tuning due to it only happening when running anything but stock but could be wrong.

I have a 1999 F350 200,000 miles. Now getting an intermittent engine light. Still runs well, although once or twice I felt a momentary surge at highway speeds. The light is on intermittently about 1/2 time. I read the codes and the following codes, as in the thread title, came up:
P0280 - ICP circuit out of range - low
P0113 - intake air temp sensor circuit - high input
P0470 - Exhaust back pressure sensor circuit malfunction
P0478 - Exhaust pressure control valve - high input
What would make these all code at the same time? Would these not make a noticeable problem driving? And how do I resolve these?
Ford 7.3L Power Stroke (1999-2003) :: F250 - Code P1211 - Service Engine Light Pops Up Going Steep Hill
I have 2003 f250 7.3 automatic 181,000 miles completely stock. Never had chip,tuner or anything on it. I am second owner and got it when it had 70,000 miles on it. Ok here we go I live on top of a mountain and soon as i start up the mountain or any steep hill, or pull or tow something my service engine light pops on. First time it came on I took it to diesel shop they hooked it up to scanner and said it was code p1211 said icp sensor was bad so they put new one on. Couple days later light started popping back on so i decided to order a auto ingenuity after doing some research.
Hooked up to truck started up mountain while scanning at wot light pops on code p1211 and think it was live data I remember seeing icp pressure at 1922 and duty cycle at 63% i was trying to drive and read it at same time and my lap top went dead. What does this reading mean 1922 pressure/ at 63% cycle done little research but dont really understand. Year and half ago replaced all orings on all injectors, new rebuilt hpop pump. New ipr valve, glow plugs, past month 2 different icp sensor new,and new ipr valve new pig tails on both and light still popping on.
Ford Excursion :: V10 4r100 Transmission - RPM Dropping When Climbing The Hill
Today I was 160 miles into a 250 mile drive and things were going well. I was cruising at about 75-80mph and approaching a fairly long hill of moderate grade. As I climbed the hill, my rpm was dropping, as expected before a downshift. The downshift never happened. I kept pushing more pedal and eventually, at maybe 40mph, it downshifted, but still no power. Engine being held at around 2500 rpm. No power no matter how much I pushed. Down hill I was able to resume speed but as soon as the next uphill, same thing, no power, no shift. Pulled over, it was raining hard. Checked for wet fuse box, control modules, pcm, wiring harnesses, everything dry. Checked all fuses. Disconnected battery in hopes of forcing reset, no change.
Checked trans fluid, it was clean, red, full, and unburnt. No visual wires broken or chafed. No odd smells or sounds. Nothing noticeably hot. Truck hits 45mph max on flat ground. I limped it this way for 20 miles. If I push my foot to the floor to really force a downshift, engine will rev freely up to redline with no resistance once it downshifts. If I let the rpm drop down, it will catch and lock back in. Now when I come to a stop the truck has a very lopey and rough idle and will stall once I come to a complete stop. It will stay running if I give it gas. In neutral and park the engine still has a lopey idle and is rough. Will possibly die at times. Sounds smooth and perfect when you rev it in neutral or park. Reacts as it should with no hesitations. No check engine light and no flashing OD light. Will shift into all gears, just moves through them with no power. Let truck sit for 3 hours, issue remains.
Ford F-150 (2004-2008) :: Truck Would Bump When Climbing A Hill While Under Load
2006 fx4 f150 5.4 flex 52,000 miles ... Just got home from a 800 mile round trip vacation, seems I've developed a miss or a tranny problem. The truck runs/idles fine, shifts fine, everything is as normal. Except maybe 12 times while under a load, like climbing a hill, the truck would "bump" that's the only way I can describe it. I only noticed it in Drive/Overdrive. I hoped I had water in the gas so I added gas treatment at 2 fill ups, still seems to do it occasionally. Where to start? I'm going to get a fuel filter today, the one that's on it only has about 12k on it....
View 13 RepliesFord Excursion :: Rumbling Vibration And Noise While Climbing A Steep Paved Hill At 5 - 10 MPH
Ok...not sure were to go with this or how to explain it, while climbing a steep paved hill at 5-10 mph I get a rumbling vibration and noise. If I were to guess almost like axle wrap is causing the U Joints to bind or something. Runs and drives fine other then that. If I put it in 4x4 it does not happen, only seems to happen when wheels cant slip while climbing hills at LOW speed.
Don't notice it if climbing a dirt hill. There is a hill at the kids baseball fields that is steep and paved that its really bad on, way to busy right now to play on it to see what's happening. Tranny was looked at and oil changed.
New BDS 4" lift - had same issue prior to lift, though stock springs were worn.
Searched the form but really didn't come up with anything at this low of speed. While in Wisconsin the resort we were at the paved hills were so steep it felt like something was going to break. Put it in 4x4 and it was fine. This was with stock leafs.
Ford 6.0L Power Stroke Diesel :: 2003 - Surge At Idle After Driving For A While
My 2003 6.0 has started to surge at idle after driving for awhile. Like when I drive to work (30 min) and pull off the interstate the idle will bounce around at the stop sign (only jumping like ~100rpm). Does this sound like the ICP to you? I've replaced it once before and am wondering if it's time to do it again?
Also the truck will sometime be hard to start. And when I say hard to start I mean turn the key, let the GP cycle the turn to start and it just cranks. But as soon as I turn the key back off and cycle the plugs again it'll fire right up. It doesn't seem to matter if it's hot or cold. It's been doing it since I got the truck. It seemed to get better after the 1st ICP but didn't completely get fixed.
Prius (2004-09) :: Engine Rattles When Climbing A Hill With AC On
My wife has an 08 with a little over 50k miles. When under load (climbing a hill) with the AC on, the engine "rattles". This sounds like classic detonation to me. It stops when I turn off the AC or she lets off the gas. I have tried running several tanks of super unleaded with no improvement. I have searched here and checked a few things others have mentioned as well, such as a loose hood prop rod with no success.
The car just started doing this around 3-4k miles ago. Last week I changed the spark plugs, even though they are way under the mileage where I should change them. The plugs looked normal, a light tan color, with no unusual deposits or anything out of the ordinary. . Last night I checked and the engine coolant was a little low, so I topped it off. This had no effect as this afternoon on the way home I heard the same clatter when climbing a long hill. All this started back in march when the outside temps were still in the mid 80's... I wonder if it is possible that the pistons already have carbon at this low of mileage ?
Toyota - Corolla :: 2010 - Horrible Noise While Climbing Up Icy Hill With Traction Control?
2010 Toyota Corolla, 5spd. I was trying to get it up a snowy/icy hill this weekend and, although I succeeded, the car made a very scary noise that I couldn't decipher. Here's what happened:
When the traction control engages, it makes a sound like the ABS engaging. That wasn't the noise that worried me. I was feathering the clutch and trying to massage the car up the slippery incline, and it started making a loud rhythmic banging noise. It sounded like what happens when you're parked and you think the car's off, but it's not, and you take your foot off the clutch. The clutch engages and makes a bang, and the engine stalls. (Not that I've ever done that before.) That's what it sounded like going up the hill, but about twice a second and very steady.
As soon as I heard it, I tried releasing the clutch pedal all the way, I tried feathering the clutch more, I modulated the throttle a bit, but honestly I was 3/4 of the way up the hill after 45 minutes of trying and I didn't want to stop! So I bang-bang-banged twenty feet up the hill or so, then when I stopped at the top the car seemed fine. I've since driven it another 300 miles of city and highway and no issues whatsoever.
Now, I've driven stick for twenty years and dozens of cars and am very comfortable in my own skill. This clutch has always seemed a little screwy since we bought the car, but the dealer mechanic told me (when I mentioned it early on) that it's normal. It's hard to describe why I think it's screwy but it doesn't feel like any other clutch I've driven, new or old. Including, every once in a while, when I'm pulling away from a stop sign in normal (dry) conditions, the clutch will chatter a couple times as I engage it. It's far from a consistent or reproducible problem, and I always wrote it off until this recent episode that sounded/felt similar but much much worse.
Could there be oil on the clutch plates? Could this have something to do with the traction control.
Prius (2010-12) :: Burning Rubber Smell After Climbing A Moderate Hill At 40kph / 25mph
I had a very strong burning rubber smell coming from under my Prius tonight after climbing a moderate hill at 40kph/25mph for approximately 3 to 4 minutes. The car had been driven for about 50 minutes through regular traffic, outside temp was 7C/44F and I drove up to a scenic outlook. When I pulled into the parking lot, we put the passenger window down and the burning rubber smell was very strong.
I searched all around using a small flashlight and couldn't see anything touching the exhaust, but it's difficult to see anything under a Prius with it's low ground clearance. The burning rubber smell was strongest under the car, but was getting pulled into the HVAC system when we stopped. I have smelled it before, but passed it off as other vehicles. After tonight, i'm sure its coming from my car. I drove the car home for 50 minutes through stop and go city traffic, so the engine was not always running. After parking, I checked under the car again and the smell was very light almost non-existent.
I have 13000km/8000mi on the car, and I have had it for 11months. It has been driven in hills and very hot weather last summer, so I don't think this is paint burning off or the car getting hot for the first time.
