Ford 7.3L Power Stroke (1999-2003) :: 2000 - Power Loss While Towing Up Hills?

I pulled with my 2000 F250 7.3 for the first time yesterday pulling a 12,500 5th wheel and then again today with an 18 ft ski boat weighting around 3500 for both the trailer and boat. I had this same issue pulling both.

Today when pulling the boat/trailer i was behind a slow moving truck and when we hit a hill with a passing lane i merged over and wanted to start passing him. We started off at around 45 mph up the hill and as I started pushing the pedal I wasn't gaining any speed and my rpm's didn't even get over 1500. It felt like a stall and continued that at around 45-50 mph up the hill (about a 65 degree slope). When I'm not towing the truck runs great, plenty of power and averaging around 16 1/2 mpg.

Only mods i have is a 6647 Napa filter, muffler delete and it's running the same 4 position TS tuner from the original owner. During normal operation I run it at the 75hp gain and when towing i use the 50hp gain.

In both instances i could see black smoke coming from exhaust when pushing the pedal but my rpm's wouldn't go up and truck maintained the slow speed going up the hill. Once at the top it drove normal and picked up speed without any problems.

Ford 7.3L Power Stroke (1999-2003) :: 2000 - How To Get Better Tranny Shifts

'00 PSD w/ 291k on the clock. Starts easily, runs good, only complaint is (what I consider to be) the soft shift of the tranny. Years ago, when I bought it, it came with a Super Chips Tuner. I've never max'd it out, just usually run on the performance tow. Is there any way to clean up the shifts and make them a bit quicker with less slip. When it's time to shift, dammit, I want it to "SHIFT", not slide into gear. I don't expect it to hit the gears like a manual valve bodied drag car tranny. But, there should be something to fix this without spending a bunch of $$$..

Mazda - Mazda5 :: 2007 - Runs Rough - Diminished Power For Climbing Hills

Our 07 Mazda5 (80k) once in a while will start and run very roughly, and pressing the gas to the floor only gets it to 3,000 rpms.It has diminished power for climbing hills when this occurs. Everytime this happens if we shut the car off and let it sit (between 10 minutes - a couple hours) it starts and runs like a top. We have added drygas 2 of the times, but the last time it happened was on the same tank of gas that we added the drygas to. Check engine light comes on, but will go off after a day or so.

Gasoline - Hyundai - Elantra - Transmissions - Clutches :: 2002 - Losing Power When Climbing Hills

Our 2002 Hyundai Elantra is having issues. It shifts fine, no need to double-clutch. It stays in gear. Doesn't grind or anything crazy like that. It does seem like it isn't getting power to the drivetrain, and is having trouble climbing hills. This all came on very suddenly. Hubby thinks it's the clutch -- I think it may be the bushings. Though now, I'm wondering if it's something else? Since it's not having trouble shifting, should we be looking at the fuel system? Sensors? Engine seals?

Ford Ranger / B-Series :: AC Changes Modes Climbing Hills

I've been driving my 99 ranger 2.5 now for 2 weeks now. Overall I am very impressed and happy with it. Everything seems to be near perfect and in top shape on this truck and I feel like it'll have no problem paying me back.

I've recently noticed, however, that whenever I start up a hill with the climate control on, it shifts from whatever I set it to, to the defrost vents. It returns to the vents I set it to after I crest the hill, and doesn't change vents if I don't drive over hills. I live in a hilly area so that's not convenient. And with summer around the corner, I want this solved.

Ford F-150 - 1997-2003 :: Hesitates / Surges When Climbing Hills

03 supercrew 5.4. I've been having problems climbing hills. I'm on a trip and the truck surged fron do then to drive and stopped. Let it sit for 30 mins or so and it was good. Drove another 500 miles ans started again going up some hills. The first time it was 110 out and the 2nd it was 90. I'm pretty sure it's a cop but of course no cel. It does not seem to of over heated either. Can the cops overheat? Do you recommend a diagnostic, will this show up if no cel has show?

Ford 6.7L Power Stroke Diesel :: 2011 - DTC P0401 / Significant Loss Of Power On Hills

Getting DTC P0401 on my 2011 with 92K miles. First time I got the CEL, we were on vacation, so I read the code, took a screen shot, then cleared it. Called my normal dealer, setup an appt, verified that they thought the truck was safe to drive. Coming home from vacation, I was pulling the TT in my sig, and noticed significant loss of power on hills that I have pulled many times before that I couldnt even hold 55 on now. Transmission dropped into 4th a couple times, on hills that it would sometimes stay in 6th, or at most drop to 5th.

CEL stayed off for a week , and came back on again. The funny thing is that after a day or 2, the CEL went back out on its own. I read the codes the P0401 is still there as a stored code(I did not clear this time). Around town the truck drives fine, the only thing I noticed was the decrease in power when towing. Truck is at the dealer now. TECH "isn't convinced" yet that there is a problem. He is not finished diagnosing yet, and I am sure that he has specific tests to run, but I am starting to fear that I will be getting the call to come get my truck.

Ford Escape / Hybrid :: 2005 2.3L - Loss Of Power / Struggles On Hills

So my wife's 2005 escape has been slowly losing power over the past 6 months or so. I regularly change the oil, tried new spark plugs, new air filter and still it's lazy. I know it's not a race machine but it struggles on hills.

This winter it was having problems starting unless the accelerator was pushed to the floor. After a cleaning of the Idle control valve all was well again. It has roughly 72,000 miles on it and uses .5-1qt of oil between changes.

Ford Super Duty (1999-2016) :: 2000 F350 - Transmission Shifts Fine With Disabled O/D?

And if I have to sift through one more "My O/D light is blinking."

I have a 2000 F350 7.3 4x4 SRW CC with several issues but right now I'd like to address the one plaguing my transmission. If I crank the truck and take off it will not shift out of first gear, well it might but it'll take a while, be at high rpms, and a hard shift, throwing the 1-2 shift error code. Now if I disable O/D with the button on the shifter and take off it shifts through all gears fine. I can drive it normally and if I hit the highway, when I'm up to speed I can enable O/D, it shifts into O/D and I can keep on trucking. When I stop I disable O/D and take off normally again. After about 10 minutes of driving and several start/stops even with O/D disabled it will eventually throw the 1-2 shift error code and give me a harder shift into 2nd and I guess enters its limp mode but is still drivable. This appears to be the only code dealing with the transmission.

Due to the fact that it shifts fine with O/D disabled, doesn't skip any gears, and I can manually shift it through 1-2-D I'm guessing it's not the mechanical diode I've heard so much about but an electrical issue. Before I bought this truck it had been abused, at one point the front driveshaft came loose and ripped the wiring harness going to the TRS in half. They soldered it back together but it still looks a little rough. I figure this is a good place to start. What readings I should get at the TRS? Sensor side and plug side. I have the AE enhanced ford bundle and a good DVM. If the TRS can't cause an issue like this where do I go from here, shift solenoid?

TLDR Version
2000 F350 7.3 4x4 SRW CC
Won't shift out of first with O/D enabled.
Shifts fine with O/D disabled.
Can manually shift through all gears.
Eventually throws 1-2 shift error code.
TRS/TRS Harness has been damaged in the past.
Appears to be an electrical issue with the transmission.
Can the TRS cause an issue like this?
How do I test the TRS/Harness?
If not the TRS what could it be, shift solenoid?

Hyundai - Elantra :: 1997 - Emits Blue Smoke From Exhuast While Climbing Hills

1997 Hyundai Lantra LS 1.8 5-speed. I live in a really flat area, but we're surrounded by hills and mountains. Whenever I have to go into the mountains I start to get blue smoke from the exhaust after a few minutes of climbing. The longer or steeper the hill, the more smoke I get. Obviously I'm burning oil, but I'm not sure what would cause the problem only when the engine is being taxed.

Subaru - Outback :: 2002 - Engine Temp Increasing When Climbing Steep Hills

I am having an engine temp issue when climbing steep hills. The gauge goes from normal to the red line but not into the red. The VDC OFF light is on but the CEL is not one. Once I reach the top of the hill the engine begins to cool off and returns to normal. Yesterday I had the radiator flushed and the thermostat changed. Am I looking at a water pump or head gaskets?

Nissan - Frontier :: 2002 - Temp Needle Near Danger Zone While Climbing Hills At 40mph / 2500 Rpm

I have a 2002 Nissan Frontier with a non supercharged 3.3L v6. The truck is a crew cab, long bed and 4x4. I have had this truck since I bought it used in 2004 with 26k miles. The truck now has 196k miles and I have done a little modifying to make it a bit more off road capable.

I have done all the work to the truck myself, until last fall when I finally broke down and took it to a dealer, who was not able to find my problem, but I will get to that...First of all, the truck has steel bumpers, a winch, a tool box, onboard air system and large tires, all of which make the little 3.3L work hard. However, for three years since I quit making modifications, the truck ran perfectly cool and the temp needle never once went above the normal operating position, even through thick sand at the beach, mountain trails and towing heavy trailers, until last summer.

Late last summer, on 90+ degree days, I noticed the temp needle would start riding above normal when I had the AC on. It didnt matter if I was on the highway, the city streets or idling in the driveway. When I turned off the AC the needle went back to normal. This started happening occasionally at first (once every 2 weeks) then towards fall it started happening more frequently, almost every 90 degree day. Soon after I noticed the problem, it would happen even with the AC off, but not get quite so hot.

After a few weeks of this, I started chasing the problem. I replaced the radiator cap, the thermostat (tested the old one and tested the new one before installing,) I took the radiator to a rad shop and had it boiled and flow tested, I replaced both coolant temp sensors, and then finally the water pump. When none of those repairs made a difference I built new radiator fan shrouds and that made no difference. At this point I was starting to get discouraged so I borrowed a scan tool from a friend and drove around for a few weeks with it plugged in. I was reading live temperature readings of the coolant and verified that the gauge was working correctly.

The truck ran about 200 degrees with the AC off most of the time, then, when I turned the AC on, no matter if I was sitting in park or driving on the highway, the temp would steadily climb until it got to 222 degrees and I would shut off the truck, at that point the needle was near the danger zone and according to several nissan dealership, the highest normal operating temp is 204, but it should stay around 195. At 205 degrees, the needle would start to move above the normal position, so the gauge seems to be fine. As summer turned into fall, the truck started running cooler as the days began to drop into the 70's. I finally got fed up with chasing my tail and took the truck to a dealer with my main concern being a blown head gasket or cracked head.

The dealership inspected the head and tested the coolant for hydrocarbons and said that the head and gasket are not the issue. They advised that the only other thing it could be is my fan clutch. After that dealership visit, the days were cool so I drove the truck all winter without changing the fan clutch. Then, 2 weeks ago, on a 70 degree day, I hooked up my truck to an empty trailer (maybe 1000lbs) and towed it 15 miles. When towing up hill with the AC on, the temp needle started moving. I immediately went to napa and replaced my fan clutch. Confident that was the issue, I drove the truck to the mountains for a camping trip last weekend. While climbing the hills at 40mph and about 2500 rpm, the temp needle climbed to the near danger zone.

Camry :: Power Loss On 2003 XLE / Not Accelerating Or Going Up Hills

My 2.4L 03 XLE with 220k on it is losing power. Running fine other than not accelerating or going up hills as well as it was last week. I have P420 cat code for the past 40K. It also has the typical smoky start from leaking valve seals and uses about a quart every 1k miles.

Ran a can of 44k through it and I'm about to pull the plugs and see what shape they are in, but I'm wondering if this loss of power might be the cat. I've been searching and it seems a plugged cat is a common cause for power loss. Seems likely since I use so much oil.

Seen the DIY replacement and leaky seals Rockauto suggested replacement Eastern ECOIII as well as the Walker.

Ford - Explorer :: 2000 - Loss Of Power - Truck Is Rocking Side To Side When Driving

So after getting home last night and having a lot of trouble backing into the driveway, having a serious loss of power, I take it out today and find that the truck is rocking from side to side as I drive, a bit like a boat in rough water. Further, I wasn't able to get much power out of it, capping about 20mph/30kph. Reversing produced some ugly grinding or scraping noises. The steering wheel swung very quickly back to its neutral position after turning, and I've noticed a strip on the road near the driveway where I apparently spun one of the tires trying to back in. Some quick searching says it could be a wheel bearing, an axle problem or suspension-related.

Subaru - Outback :: 2004 - Loss Of Power On Hills - Leaky Head Gasket?

My 2004 Subaru Outback has had the head gasket replaced, the O2 sensor replaced, spark plugs replaced. Still I cannot go up big hills anywhere near the speed limit. I think it may be the catalytic converter is bad from driving it with a leaky head gasket.

Santa FE SM (2001-06) :: Tranny Slipping - Power Loss When Going Uphill And Has To Downshift

I just recently bought an 06 Santa Fe with a 2.7l v6. It was a rebuild. It had been hit in the left wheel. The lot put a new fender, suspension parts, axle, etc. It only has 25k actual miles.

We took it on a 100 mile trip today. I noticed if I am going up hill and it has to downshift, it feels like it looses power. The car continues to slow... Like the tranny is slipping. I stopped at Walmart and found the tranny fluid wouldn't even register on the dipstick. I bought Valvoline max life tranny fluid that matches the sp3 specs in the manual. I had to add almost 3 quarts before it was full. I think they may have forgot to add fluid back to replace what leaked out after they replaced the axle It didn't seem to work though when I continued to drive. After I stopped and let it cool about 30 minutes, it did seem a little better.

I guess my question is should I replace the tranny fluid? If so, what should I replace it with? Is there anything else what could be causing this now?

Ford 7.3L Power Stroke (1999-2003) :: 2000 F250 Runs Out Of Fuel On Hard Pull / Long Hills

Every time I hit a hill, loaded or empty, or get on the truck on level ground after about 15 seconds it acts like it's running out of fuel. The pump starts getting noisy like it has air in it, but it'll straighten out eventually. If you don't let off the fuel it'll eventually stall out. No check engine light, no codes. Truck has a ts chip but it does it on all settings. New fuel filter, changed oil with hot shots secret, new air filter, hutch mod done. I'm at a loss for what to do. Good fuel pressure also.
