Toyota - Celica :: 1987 - Suddenly Revved Into Higher RPMs While Slowing Down
I was driving home from campus yesterday, and as I approached about 50mph, the Celica suddenly revved into higher RPMs, all the while slowing down. I pushed the gas pedal, which only worsened the problem. I was able to limp the car home. About an hour later, I tested the car again, and the problem remains: Accelerate to about 35-50, then get high RPMs while the car slows down and jumps forward.
I suspect a transmission problem, accentuated by a loose wheel bearing that I haven't been able to afford to get fixed yet. My Celica is an automatic, with about 213000 miles on it.
Toyota - Camry :: 2002 - Engine Suddenly Revved Up To 4200 Rpm While Going Uphill On Freeway
While driving with cruise control set at 80 mph in my 2002 Toyota Camry, the engine suddenly revved up to 4200 rpm while going up a hill on the freeway. I was wondering if this sudden high rpm could do damage to the engine? The car has 163,000 miles on it.

I drove my car to work today and no problems. Tonight my wife and I took the car out to go to dinner and intermitantly there and back my car is hesitating as we drive along. I thought it was odd at first then my wife asked if I was kidding around. I told her its not me.
It's as if the car is driving then all of a sudden its like a loss of power or as if the limiter kicks in and starved the engine of gas and then a second later it jerks back to life and keeps going.
If it does this tomorrow its going to the dealer. It is not throwing any warning lights and I have 3/4 tank of gas so its not that.
Santa Fe (CM - 2007-12) :: Power Loss Suddenly When Driving On Highway At About 80-90 Kms/hr
I am using a Hyundai Santa Fe (Petrol, 2011 Model) here in Saudi Arabia. On July 17 (11:30 pm), I was driving in a highway at about 80-90 kms/hr when suddenly my vehicle lost power (steering wheel, brake, etc).
Baed on the diagnosis of our company mechanic, it was an alternator problem. He said the alternator bearing got stuck up.
Prior to this incident, on July 7, the same vehicle got stalled twice while it's parked. In the first case, I was able to use it after jumpstarting. In the second case in the same day (4 hours after the first case), jump starting didn't work so they have to replace it with a temporary used battery. I noticed that I had a hard start (the engine responds only after 3-4 key ignition). After replacing the battery with new one, I was able to drive normally from July 9 to Jul 17, and then the incident happened as I described in the first paragraph.
Question: Is there a way to detect the alternator bearing problem before it actually breaks down? If there is, what procedure or predictive test is normally followed to identify potential problems in an alternator?
Sonata I45 (YF - 2011+) :: Complete Loss Of Power Suddenly Then Reactivated On Its Own
My son is primary driver of our 2011 Limited with push-button start. He phoned me a few minutes ago to tell me he was driving--everything normal-- when there was suddenly a complete loss of power, mechanical and electrical (engine died, dash lights out, nav screen dark, etc.). There was no advance warning of any kind.
The power loss was total but brief, two or three seconds, and then reactivated on its own. My son said he pulled off the road into a parking area, stopped the engine, waited a few seconds and then restarted and is on his way home with everything working normally so far.
First issue with the Sonata--61k miles ....
Ford 6.0L Power Stroke Diesel :: 2004 - Turbo Would Not Spool Until Revved The Engine Hard
It started after a blue spring upgrade. my turbo would not spool until we revved the engine hard then it kicked in and it's kinda worked since then.. it feels like the truck is struggling on acceleration and the boost builds fast up to 30lbs, the EBP seems to be stuck at 21.48psi until your in 3rd then it jumps and I have power again, also the turbo dumps (farts) if I let off even a little until the EBP jumps then no issues. I replaced the sensor and it's stuck at 21.48 all the time.
Now, I unplug it and it jumps between 26 and 28psi, plug in the old sensor while it's out laying on the motor (not installed) and right back to 21.48. I don't know where to go with this and it's my only truck so I need it running. also it was blowing the intercooler boot off at the turbo during a normal acceleration and the turbo spool has a howl to it when EBP is stuck...
Prius (2004-09) :: Power Loss In Mountains?
I recently bought a 2004 Prius with 104,000 miles on it. When I try to go up into the mountains I only get a few miles or up to 1,000 to 2,000 ft. elevation (from 300 ft. starting) and the battery level gradually drops from 6 bars to 1 bar. The red triangle light and check engine light comes on and the car speed gradually begins to drop even if I continue to press on the gas pedal. I have only gotten down to about 35 MPH from 60-65 mph before stopping and turning around. Within a few miles of turning around the light goes off and the battery goes back up to 6 bars and works good going down hill. The dealer I bought the car from has been working with me to figure out the problem but so far we have not figured it out. He has replaced the main battery as well as the inverter/converter. The mechanic was with me on a test drive to the mountains and had his car computer plugged in while we drove and experienced the same thing. It gave the code for the catalytic converter so we changed the entire CC/muffler (one long piece) and still got the same code. The battery indicator on this car has never shown more than 6 bars. I'm not a Prius mechanic but I personally think it has a bad "Gas Engine" or something wrong with the gas engine. How do I tell if the gas engine is bad or has a problem?

I have a 2008 Prius with about 95,000 miles. It is bloody cold here. About 4 degrees F when I got up. On the way to work, on the parkway, suddenly the car lost power entirely. Just started to slow down. No reaction when I pressed on the gas pedal. I didn't notice any warning lights. I flipped the gear shift to Drive, and the car accelerated again. About five minutes later, this repeated. For the rest of the trip it was fine, and there were no problems coming home. (Temperatures were still way below freezing in the afternoon when I left work though the car had been sitting in the sun. I don't know if this could be cold-related, but it's never happened before and it hasn't been this cold here for days on end before._

My friends 2004 6.0 f250 has 280000 miles on it and it runs perfect "did" until I tuned it with my sct tuner to run a looney tune so he could see what it was like. The truck started he revved it up to 3'000 rpm then when it returned to idle it acted like someone shut the key off. The high pressure oil system is new and has 700 psi and the icp is good also the ipr. The truck Is not getting any fuel at all, no smoke from cranking at all. It is returned to stock and is still being difficult. It has fuel I checked the upper fuel filter, it has enough oil, and it also has a good motor just don't fire. Why?
View 3 RepliesPrius (2004-09) :: 2006 - Red Triangle And Loss Of Power
Purchased a used 2006 prius with ~180K miles on it from south bay a few months ago. At the time of purchase the guy warned us that it 'ate' motor oil.
After 2 months of driving without issues (driven couple of hundred miles), on an uphill road the engine overheats and throws the red triangle, vsc and check engine lights on the dash, along with loss of power. After cool down I check oil level and sure enough it is low, since this is on top of a hill we essentially coast all the way back home without any real issues. Once home I top up the oil. I do a test drive around the block without issues (no loss of power) though the check engine/red triangle/vsc lights are still on. But after I take it for a longer drive the loss of power returns.
Since my bluetooth obd2 connector wasn't working I borrow one from my friend and try to get a read. Unfortunately the thing puts out no obd2 error codes. Living in the bay area I apparently cant just take it to an autozone, to get code readings. I take it to meineke auto repair, they too are unable to get an obd2 read, and want to charge me $100 for a full reading, which I decline.
I do a few diagnostics steps including 'resetting' the computer by leaving it off of the 12v battery for a few mins, this clears the red triangle et al on restart. I do a test drive, at first everything is working just fine, but after about 10 mins or so of driving the red triangle/check engine/vsc lights returns, along with loss of power. (under ~20 mph only, cant go uphill).
Take it to a mechanic and they come back with code: "APOA92. Trans Axel issue - MG1 performance is off. Measured torque is different than executed torque, enough to be a problem. 95% sure it is the transmission." I still haven't checked the 12v battery.
Prius (2004-09) :: 2007 - Total Loss Of Power?
I drive a 2007 Prius, I just purchased it about four months ago. Today after filling up with gas I drove about 60 miles and suddenly three lights on my dash came on. The all system light (the red triangle), the check engine light as well as the VSC or VCS what ever way it goes, my electric batter was also low on charge having only one bar(my car is not a plug in, the battery is recharged by the engine) then the car lost all boost and while pressing on the gas it was not accelerating. I pulled over and put it in park so the battery could charge. It charged to half way, however the lights stayed on.
My car then started running really rough, I am still in park at this time. I put some gas stabilizer in my tank because I thought maybe I got some bad gas. I left my car sit for about five minutes before turning it back on. All the lights were off except my check engine and my car started running normal. Then about three minutes later all the lights came back on and the car started running jerky again. When I push the gas to move I can, however I've only gone about four feet because it is running so rough.
Prius (2004-09) :: High RPM Loss Of Power - Fluttering Noise From ICE
With only 356k miles on my 06, I'm now getting a sudden drop/loss of power at high RPM. At about 80mph on flat land (or about 60mph up hill) if I try to accelerate the power drops off as a fluttering sound starts (not engine knock). The fluttering sounds like 6 inches of celophane tape flapping in the wind at highway speeds.
I just cleaned my K&N air filter, but the plugs, injectors and fuel pump are original. I ran 1 can of injector cleaner (SeaFoam from O'Reilly) with little to no improvement. I'm guessing it's the fuel pump/pressure, since it runs fine at lower RPM, with no loss of mpg or power (still 50mpg average). I know the fuel pump is in the tank ($400 in parts alone). I'll see if I can measure the rail pressure with Torque and my CANBUS scanner.

Had A/C go out while in Vegas almost 2 weeks ago. Dealer said compressor dead, replaced at my dealer back home, now having loss of power issue's, poor acceleration, 29mpg, & bad smell like transmission fluid or catalytic converter... Problems noticed after picked up car, then went away, now back.. No codes on the scantool, no lights etc.
View 6 RepliesPrius (2004-09) :: Cruise Control Dropped - Loss Of Power
I had the cruise control set on the speed limit going up a hill. Half way up, the cruise control dropped as did my speed from 70 to 56. There were no warning lights but the battery meter was in the one bar pink range. I managed to continue up the hill at 56 mph by flooring the accelerator. When I got to the top and started to regenerate power to the battery, I regained power and speed. I am discussing a 2008 Prius with 89k miles. What the issue may be ( like battery pack declining efficiency)?
View 15 RepliesToyota - Prius :: 2004 - Power Loss And Fluttering Noise
We are original owners of a 2004 Prius with 165K miles. We've taken excellent care of what has been a great family car. A couple of months ago, we got a check engine light associated with a catalytic converter error. We first replaced the oxygen sensor, which temporarily eliminated the error light, but the car really loses power, especially when a load is placed on it going up hill. The power loss is associated with a fluttering noise coming from within the engine and the battery display showing that it is not charging sufficiently.
We took it back to the dealer and they replaced the exhaust manifold gasket and suggested we replace the catalytic converter (> $2000) but also recommended a local exhaust specialist who could replace the catalytic converter for much less. The exhaust shop examined the car and told us the catalytic converter was fine and did not need replacement. There are no more error codes, and the dealership and their service department shows no interest in repairing our car.
Prius (2004-09) :: Warning Lights Came On - Gas Engine Loss Of Power?

View 18 RepliesPrius (2004-09) :: Hesitation And Power Loss - Water In Gas Tank
Hesitation and power loss have returned. I removed all four spark plugs and found that the spark plug on the driver side of the engine, or side closest to the inverter, and its coil pack were covered in dried/sticky oil with no loose oil present around them. Pics added to new post #11 of coil pack and spark plug.
I couldn't find anything that really matched the symptoms I was having this afternoon on the way home from work. After letting the engine idle for about a minute to get through Stage 1, I pulled out of work but noticed I kept hearing a slight whining from the inverter (radio was off and windows were down) while going uphill on the road out of our parking lot. Speed was in the range of 25 to 30 MPH.
Torque showed I was pulling between 10 and 20 amps from the HV battery but what I noticed that was REALLY weird was that the timing advance gauge showed I was running around 2 to 3 degrees (?) instead of normally being around 13 or 14+ depending on how quickly I'm accelerating.
And the more acceleration I demanded, the the more amps were coming from the battery and the RPMs on the engine would go up, but the timing advance still remained below 10 degrees. I didn't hear any knocking but I could definitely feel the lack of power.
Prius (2004-09) :: Loss Of Power / Red Triangle And Hybrid System Warning
During a highway trip three months ago, my 2004 Prius suddenly lost engine power, the red triangle Master Warning light came on accompanied by a warning sound, and then the Hybrid System Warning sign appeared on the Multifunction Display. I pulled off to the side of the road and stopped. I turned the car off and then tried turning it on again. Engine power was restored although the warning lights remained. We took a chance and carried on with our trip. The same sequence of events reoccurred about 10 times on our 1,300 km journey. I took the car to a Toyota dealer where they found a C2318 DTC. They checked the battery and the HEV fuse but could not locate the problem.
We returned home and on the way the same thing happened a few more times. My service manual noted that the description for C2318 is Low Voltage Error (Power Supply Malfunction) and the trouble areas are HEV fuse, IGCT relay, Wire harness or connector, or Auxiliary battery. Since the car was nearly 7 years old I thought I had nothing to lose by replacing the battery, which I did. However, on a short 150 km trip last week the problem appeared again, once while approaching our destination and once when we were almost home. There seems to be a pattern in that the problem appears every 150 km or so of highway driving. It has never done it while driving in the city.
